Here's a quick recap of what's happened so far:

• Early Wednesday morning, India launched several air strikes on Pakistan and Pakistan-administered Kashmir
• Delhi said it targeted nine sites. Pakistan later said six locations were hit
• Islamabad has claimed several times that it shot down five Indian jets and two drones, which India has not confirmed
• Pakistan said 31 people had been killed and 57 injured in India's action
• India's army said at least 15 civilians and one army personnel were killed by Pakistani shelling on its side of the Line of Control (LoC), the de facto border that divides Kashmir between the neighbours
• Cross-border shelling continues at the LoC. India says it's responding to "unprovoked firing" from Pakistan's side
• India has held civil defence drills across the country
• The Indian government has called an all-party meeting today to brief political leaders on the strike
• Iran's foreign minister is in Delhi for bilateral talks

We asked Husain Haqqani, a former Pakistani ambassador to the US, for his perspective on the current crisis with India unfolding on Pakistan’s soil.

"The Pakistani military has already regained the popularity it had lost in its tussle with former Prime Minister Imran Khan and his supporters. Any conflict with India, especially over Kashmir, always rallies Pakistanis to their military," he said.

We asked how concerned he was that this could escalate into an unprecedented crisis - or whether he believes there’s already an off-ramp available.

"India and Pakistan have been through this cycle for three-and-a-half decades, and even after both turned nuclear in 1998 this cycle has continued," Mr Haqqani said.

"I hope that after a potential Pakistani strike, the off-ramps that are available will be used. But if the two sides get into further cycles of retaliation, we will have a bigger crisis on our hands."

Mr Haqqani said the Indian strikes were "predictable".

"It was predictable that India would respond, with a strike that was punitive but would not seek to escalate the situation."

Early Wednesday morning, India launched air strikes into Pakistan and Pakistan-administered Kashmir, two weeks after 26 people were killed in a deadly militant attack in Pahalgam town. Islamabad has denied any involvement in the attack and called the strikes "cowardly".

Meanwhile, world leaders are calling on both India and Pakistan to de-escalate as tensions continue to rise.

Here is a quick recap of what has happened so far as BBC reporters on the ground continue to bring you the latest updates.

Iranian Foreign Minister Abbas Aragchi has arrived in Delhi to hold talks with officials here.

An Indian foreign ministry spokesperson said Aragchi's arrival was an opportunity "to review and enhance bilateral cooperation on the 75th anniversary of the India-Iran Friendship Treaty".

Aragchi was in Pakistan a day before India launched several airstrikes into Pakistan and Pakistan-administered Kashmir. In Islamabad, he met with his counterpart Ishaq Dar.

Iran had earlier offered to mediate between India and Pakistan in the lead-up to the recent clashes.

If you're just joining us, here is what we know about recent developments.

Two weeks after a deadly militant attack on tourists in Indian-administered Kashmir, India has launched a series of strikes on sites in Pakistan and Pakistan-administered Kashmir.

The Indian defence ministry said the strikes - named "Operation Sindoor" - were part of a "commitment" to hold "accountable" those responsible for the 22 April attack in Pahalgam, Indian-administered Kashmir, which left 25 Indians and one Nepali national dead.

But Pakistan, which has denied any involvement in that attack, described the strikes as "unprovoked", with Prime Minister Shehbaz Sharif saying the "heinous act of aggression will not go unpunished".

Sharif on Wednesday said the Pahalgam attack "wasn't related" to Pakistan, and that his country was "accused for the wrong" reasons.

A former senior British diplomat has told the BBC News Channel he’s worried about a possible escalation that “could be quite fast”.

Tim Willasey-Wilsey, who was posted to Pakistan in the 1990s and is now a visiting professor at King’s College London, says Indian strikes on Pakistan “have actually been quite restrained”, targeting sites linked to “Kashmiri terrorist groups”.

But he says that civilians are killed in these strikes, and that “it’s in Pakistan’s DNA to respond”.

When Pakistan does respond, Willasey-Wilsey says it will be “very difficult” for them to justify their actions, as there are "no terrorist training camps in India".

“They clearly mustn't attack the civilian population,” he says. “I suspect what they might do is go for military sites ... but even that is going to inflame passions in India.”

“And then we will be on what strategists call the escalation ladder, that could really be quite fast.”

Former Scottish first minister Humza Yousaf and former Irish taoiseach Leo Varadkar have written a joint letter to the leaders of India and Pakistan urging restraint and de-escalation.Writing as public servants and "men with roots in the subcontinent", they called on Narendra Modi and Shehbaz Sharif to "resist the pull of conflict".The former first minister is of Pakistani heritage while Varadkar's father is from Mumbai.

Pakistanis are counting their losses after Wednesday morning's strikes which Islamabad says has killed at least 31 people and injured 57.

The strikes reached the Pakistani city of Muridke where locals gathered to assess the damage at a sprawling complex.

Recounting the night's events, one man told the BBC that India's bombardment lit up the night sky.

"The sky lit up and it felt like the sky turned red," he told the BBC.

The BBC's Umer Draz Nangiana has been on the ground in Muridke in Pakistan's Punjab reporting.

As India and Pakistan's militaries clash, the US is missing a key player: an ambassador in both countries.

A locally based envoy would have had an important role during such a heightened time.

"That person could be doing things on the ground in Delhi with both sides, being quiet in diplomacy and a quiet interlocutor," Tim Roemer, former US ambassador to India during President Barack Obama's first term, told the BBC.

Having ambassadors confirmed to India and Pakistan is "essential", he said.

"We have ambassadors that have been nominated or confirmed to Israel and China and South America ... India is right there at the top in terms of importance and priorities for the United States," he said.

US ambassadors undergo a nomination and confirmation process in the US Senate which can take time - the Trump administration has just crossed 100 days.

"We sure should prioritise making this one of the first kinds of nominations we have and I am kind of surprised that we don't have a person either nominated or in place yet."

India’s strikes, which the country says are targeting "terrorist infrastructure", are an attempt to contain the situation, says Chietigj Bajpaee, senior research fellow for South Asia at Chatham House.

“It’s trying to ensure that the conflict remains below the threshold of a nuclear conflict or a wider conventional conflict between both countries,” Bajpaee had earlier told the BBC News Channel.

But he adds “it remains to be seen” if the exchange of attacks between India and Pakistan “suffices in appeasing both countries' domestic political constituencies and hyper-nationalist foreign policies”.

He also points out that, unlike previous periods of India-Pakistan hostility when the US played a “prominent role” in de-escalating tensions, there is “limited external pressure” this time.

“We haven’t really seen anything of that nature so far from the US or any other countries.”

So, attempts to contain any escalation are “easier said than done”, Bajpaee says.

Our colleagues from The Briefing Room podcast have just recorded a new episode on the rising tensions between India and Pakistan, and consider whether the two nuclear nations might be on the brink of war.

A State Department spokesperson has told the BBC, the US is "closely monitoring" the skirmishes between India and Pakistan.

The spokesperson said US officials were in touch with the two sides and was urging the countries to "work towards a responsible resolution that maintains long-term peace and regional stability in South Asia."

Earlier on, our State Department correspondent Tom Bateman said the lack of an explicit American call for restraint since the Indian strikes reflects the US’s strengthening ties with India over recent years, and the relative isolation of Pakistan.

Last night, when the fighting began, Secretary of State Marco Rubio reiterated Trump's comments saying he hoped the clashes end "quickly" and will work "towards a peaceful resolution".

Two weeks after a deadly militant attack on tourists in Indian-administered Kashmir, India has launched a series of strikes on sites in Pakistan and Pakistan-administered Kashmir.

The Indian defence ministry said the strikes - named "Operation Sindoor" - targeted what it called "terrorist infrastructure" to hold "accountable" those responsible for the 22 April attack in Pahalgam, which left 25 Indians and one Nepali national dead.

But Pakistan, which has denied any involvement in that attack, described the strikes as "unprovoked", with Prime Minister Shehbaz Sharif saying the "heinous act of aggression will not go unpunished".

Sharif on Wednesday said the Pahalgam attack "wasn't related" to Pakistan, and that his country was "accused for the wrong" reasons.

Kashmir is a flashpoint for Pakistan and India with two wars having been fought over it.

While it is claimed in full by both countries, they each administer a part of the region since they were partitioned following independence from Britain in 1947.

Malala Yousafzai is urging leaders of Pakistan and India to "take steps to de-escalate tensions, protect civilians - especially children - and unite against the forces of division".

In 2012, she was a schoolgirl in Pakistan when she was shot in the head by a Taliban gunman for going to school. Two years later, aged 17, she became the youngest recipient of the Nobel Peace Prize.

"Hatred and violence are our common enemies, not each other," Malala says on social media.

Sending her condolences to the "loved ones of all innocent civilians" in both nations, she says that she is thinking of her friends, her family, and all the advocates, educators and girls she works with in Pakistan at this "dangerous time".

"The international community must act now to promote dialogue and diplomacy. Peace is the only way forward for our collective security and prosperity," Malala adds.

A Pakistani cabinet minister has called India's strikes a "shameful and cowardly aggression", that he said targeted "peaceful civilians, including women and children".

Speaking to the BBC World Service's Newshour programme, Ahsan Iqbal says India's claim that it was targeting what it called "terrorist infrastructure sites" in Pakistan and Pakistan-administered Kashmir was "a big lie" through which it was "trying to mislead the world".

"Who are the casualties? How can be a seven-year-old boy be a terrorist? How can be a five-year-old girl be a terrorist? How can be a housewife, a women be a terrorist?" he asks.

Talking about Pakistan’s response, he said that the Pakistani government has given the armed forces "the mandate to choose the time and the manner in which we can respond appropriately".

We're hearing of more precautionary school closures in parts of Indian-administered Kashmir.

Earlier, authorities announced that schools, colleges and educational institutions in some areas would be closed today - now they say that educational institutions in some parts will be closed tomorrow too.

US taking a hands-off approachpublished at 20:53 British Summer Time 7 May

The White House is taking a hands-off approach to this crisis, characterised by Donald Trump’s Oval Office comment on Tuesday that "it’s a shame”.

Today he says there is a “tit-for-tat”, and he wants “to see it stop”, but without specifying how.

The US State Department said on Tuesday night it was monitoring the situation but is still yet to update that statement.

The lack of an explicit American call for restraint since the Indian strikes, leaving other countries to fill that diplomatic void, reflects the US’s strengthening ties with India over recent years, and the relative isolation of Pakistan, with which the US has long had a more troubled relationship.

It appears the White House has been attempting to leave Delhi with space to act. But that approach might not last long.

During the last major crisis between India and Pakistan in 2019, the Trump administration at first fully-backed what it saw as India’s right to target militants who had struck in Indian-administered Kashmir, but quickly turned to calls for de-escalation as the crisis rapidly escalated.
