Indian-administered Kashmir has seen a decades-long insurgency which has claimed thousands of lives. India and Pakistan both claim Kashmir in full
Our South Asia correspondent Samira Hussain has sent this clip from Pathankot, in the Indian state of Punjab.
Residents tell Samira they heard four blasts in total, as the impact of the blast caused all the windows to be blown out in a nearby house.
What this demonstrates, Samira says, the potential for collateral damage.

Pakistan said its forces had hit an Indian airbase, and other targets, in response to Delhi striking three of its bases.
Pakistan's Prime Minister Shebaz Sahrif said his county has given a "befitting response" to India.
India's military accused Pakistan of launching mass drone attacks along its western border, saying they endangered civilians.
Both countries say they are prepared to consider de-escalation - if the other side acts first.
Pakistan's Information Minister Attaullah Tarar said India was the aggressor in the conflict, and Pakistan had a right to respond.
India's High Commissioner to the UK accused Tarar of lying, claiming Pakistan maintained "terrorist infrastructure" inside its borders.
Meanwhile, US Secretary of State Marco Rubio says he has spoken to both countries and has urged India and Pakistan to restore direct lines of communication to "avoid miscalculation".
A Pakistani cabinet minister tells the BBC his country has shown "restraint" in its conflict with India.
Bilal Azhar Kayani tells Newshour on BBC World Service he "hopes India now realises that Pakistan does possess the right to defend itself".
Both Pakistan and India maintain their own arsenals of nuclear weapons – among only a handful of countries to do so.
So far, neither country has given any indication a nuclear attack is on the horizon. But it remains an underlying fear across the region.
Pakistan hasn't yet called a meeting of its committee that makes operational decisions on nuclear weapons, the National Command Authority, but it didn't rule it out.
"It's an option that remains with the prime minister, but hasn't been convened to my knowledge," Kayani says.
"We are a responsible nation," he adds.

Reporting from Islamabad, Pakistan
We’ve visited a market here in Pakistan’s capital, Islamabad, and while no one is panicking, several people say they feel the conflict they’re witnessing is the worst they’ve seen in decades.
As India and Pakistan blame each other for escalating violence, one shopkeeper tells me he believes the Pakistani army had no choice but to respond. But he doesn’t see an off-ramp to the conflict.
He told me, “I’m not really worried about my safety, but I don’t know how this can end. War is bad for people in both countries, no matter their religion”.
One man has a very different concern. He wants to get back home to Derby, in the UK. He said he’s monitoring airspace closures.
“We’re trying to carry on and enjoy the holiday under the circumstances.” He said he hopes at one point India and Pakistan will be at peace.

Tanya says there was smoke everywhere after her house was hit in the early hours of Saturday
In Jammu’s Janipur colony, in Indian-administered Kashmir, we met a mother and her daughter who told us they were asleep when their house was hit around 06:00.
The roof was blown, making a big hole and damaging the roof and rooms adjacent, they said.
“There was smoke everywhere, we couldn’t see anything, my mother was barefoot and her feet started burning with whatever was on the floor.
"It took a long time to open the door, but we escaped somehow,” Tanya Talwar told the BBC.
Tanya showed us the small temple they had built in the house and salvaged one idol from it, holding it close as she surveyed the damage to their home.
We've just been hearing from India's High Commissioner to the UK, Vikram Doraiswami.
He tells the BBC that India initially only targeted a "terrorist" base in Pakistan in response to the militant attack on Indian tourists in Pahalgam last month.
Earlier, Pakistan's Information Minister Attaullah Tarar said India was the aggressor in the conflict, and Pakistan had a right to respond.
Doraiswami accuses Tarar of lying, and claims Pakistan has for decades maintained "terrorist infrastructure" inside its borders.
"It's in plain sight," he says. "Ask yourself where Osama Bin Laden was," he adds – a reference to the former al-Qaeda leader's hideout in northern Pakistan where he was assassinated by US forces in 2011.

“They’ve been fighting for a long time,“ remarked President Trump when this latest crisis flared. But this confrontation over Kashmir is different in so many ways.
Old foes are now locked in their most expansive conflict in decades with both sides striking areas, including military targets, beyond this disputed region.
And they’re wielding new lethal weapons of war including unmanned aerial drones which enable riskier strikes.
Domestic pressures are also at an all-time high, fuelled by floods of misinformation and disinformation on popular television channels and social media platforms.
In past crises, restraint soon kicked in, and the US was quick to intervene. This time, Washington has been busy with other priorities.
As tensions now escalate dangerously, Secretary of State Marco Rubio has been on the phone to Delhi and Islamabad.
But it's Beijing, Pakistan’s “iron-clad” friend, not the US which is now the most important supplier of arms and funds to Pakistan’s powerful military. And influential regional players like Iran, Saudi Arabia, and the UAE, are also weighing in.
But, so far, warring sides still seem focused on this hottest of front lines.

Speaking to BBC Radio 4's Today programme earlier, Shringla blames Islamabad for escalating the conflict with high-speed missiles and drone attacks.
"Pakistan has really upped the ante," he says, adding it now bears the onus to step back. "That has really deprived the opportunity for going back to a more peaceful situation."
He adds that any escalation by Pakistan will be met with a "firm response" from India.
Image source, Getty ImagesPakistan's Prime Minister Shehbaz Sharif says the country's military has given a "befitting response" to India as the conflict intensifies.
"Today, we have given India a befitting response and avenged the blood of innocent lives," he says in a statement.
We're hearing now from Pakistan's information minister, Attaullah Tarar, who says the country's forces have a right to respond to India's aggression.
"Pakistan is not the provocateur," he tells BBC News Channel. "Pakistan now has a right to respond."
As we've been reporting, houses and cars were damaged in a civilian area in Jammu, in India-administered Kashmir, following an early morning attack, locals told the BBC.
Tarar denies targeting civilian populations. When challenged, he says the country has only targeted military installations.
Earlier, India accused Pakistan of using high-speed missiles to target its bases and moving troops "into forward areas" in an escalation of hostilities.

This is the first time a civilian area in the heart of the city has been targeted, they said.
Rakesh Gupta, a local resident, “heard a loud sound and plumes of smoke enveloped the neighbourhood".
"There was panic and chaos. Why is Pakistan targeting ordinary people?”
A few people were injured and have been taken to a nearby hospital, we were told.
Chief Minister Omar Abdullah came to the spot while the BBC team was there, but he had to leave suddenly when jets started flying overhead.
Air raid sirens were sounded and people were asked to clear out.
The UK continues to "monitor closely" the developments between Pakistan and India, Jane Marriott, the British High Commissioner to Pakistan says.
"Airspace closures are currently in place, and further restrictions may be announced or changed at short notice," she said in a post on X.
Tensions between Delhi and Islamabad have escalated further since Friday night as a series of drone strikes were reported from both sides.

South Asia regional editor, reporting from Delhi
As I was rushing from my hotel to the BBC bureau this morning, the taxi driver was anxious to know whether a conflict will break out with Pakistan.
On his phone he showed me a picture of the remnants of a projectile which he said landed close to his village, close to the border in India’s Punjab province. He said it was sent by his brother who’s living in the village.
The BBC can’t independently verify this photo, but it seems people here are now getting information from their family members living in villages and towns along the border areas.
Delhi looked normal this morning, with buses, cars and auto rickshaws chugging along, and tea sellers on the pavements.
There were reports about remnants of a projectile in the town of Sirsa, not far from Delhi, but it’s not clear who fired and where it came from.
People are realising that skirmishes are now a reality, not something that’s happening far away on the border with Pakistan. Others are being asked to stay indoors in several places in the border states.
There’s also lots of misinformation and fake news causing confusion and worry among people.
We've one final update to bring you from the briefing in India - and it comes from Col Sofiya Qureshi, who we heard from a little earlier.
Pakistan's military, she says, has been observed "moving their troops into forward areas, indicating offensive intent to further escalate the situation".
"Indian armed forces remain in a high state of operational readiness," she tells the briefing. "All hostile actions have been effectively countered and responded appropriately. Indian armed forces reiterate their commitment to non-escalation, provided it is reciprocated by the Pakistan military."
Pakistan has not commented on whether it's moving troops closer to the border with India.
Indian Air Force's Wing Commander Vyomika Singh and Foreign Secretary Vikram Misri both deny that Pakistani strikes have caused any damage to military infrastructure in India.
"Pakistan has also attempted to execute a continued malicious misinformation campaign, with claims of destruction of the Indian S-400 system at Adampur, destruction of airfields at Surat and Sirsa, Brahmos space at Nagrota, artillery gun positions in Derangyari and Chandigarh ammunitions depot, with heavy damage to other military stations being propagated on social media," Singh says, adding:
"India unequivocally rejects these false claims being spread by Pakistan."
India carried out a swift and calibrated response - forces spokesperson
We're now hearing from Wing Commander Vyomika Singh, of the Indian Air Force, who says Pakistan carried out "aggressive actions employing multiple threat vectors" around India's western border.
She says Pakistan used a plethora of weapons - including drones and long-range weapons - "to target civil and areas and military infrastructure".
"Pakistan's military also targeted air intuitions, using drones and firing of heavy-calibre weapons along the Line of Control."
Next, India's Foreign Secretary Vikram Misri tells those gathered:
"I have said on numerous earlier occasions, it is Pakistani actions that have constituted provocations and escalations.
"In response, India has defended and reacted in a responsible and measured fashion to these provocations and escalations by the Pakistani side.
"Earlier this morning, we saw a repeat of this escalatory and provocative pattern."
We're now hearing from Col Sofiya Qureshi, of the Indian Army.
She starts the briefing by accusing Pakistan of using high-speed missiles to target Indian airbases.
It comes hours after Pakistan accused India of targeting three of its military airbases with missile strikes.
While we wait to hear from Indian government officials, here's another update from Indian-administered Kashmir.
Additional Deputy Commissioner Raj Kumar Thapa, in Rajouri town, has died due to shelling from Pakistan, Chief Minister Omar Abdullah says.
"Devastating news from Rajouri. We have lost a dedicated officer of the Jammu and Kashmir Administration Services," Abdullah says in a post on X.
"Today, the residence of the officer was hit by Pak [Pakistani] shelling as they targeted Rajouri town killing our Additional District Development Commissioner Sh [Shri] Raj Kumar Thappa. I’ve no words to express my shock and sadness at this terrible loss of life."
Government officials have told the BBC that at least two more people, both civilians, have been killed in Jammu city in Indian-administered Kashmir.
We're due to hear from India's foreign and defence ministries shortly, hours after Pakistan's military said it was launching retaliatory strikes on India.
That decision came after Pakistan's claim that India had struck three of its airbases - a claim India has not commented on.
