India says it launched air strikes against militants in Pakistani territory in a major escalation of tensions between the two countries.

The government said strikes targeted a training camp of the Jaish-e-Mohammad (JeM) group in Balakot. Pakistan said the strikes hit an empty area but vowed to respond.

Relations between the nuclear-armed neighbours have been strained since a suicide attack earlier this month that killed more than 40 Indian troops.

India accuses Pakistan of allowing militant groups to operate on its territory and says Pakistani security agencies played a role in the 14 February attack – claimed by JeM. Pakistan denies any role and says it does not provide safe haven to militants.

Tuesday’s air strikes are the first launched across the line of control – the de facto border that divides India-administered Kashmir from Pakistan-administered Kashmir – since a war between the two countries in 1971.

Balakot is in Pakistan’s north-western Khyber Pakhtunkhwa province. Residents there said they were woken by loud explosions.

Pakistan condemned the strike and said it would respond “at the time and place of its choosing”.

Indian Foreign Secretary Vijay Gokhale told a news conference that the strikes had killed a “large number” of militants, including commanders, and had avoided civilian casualties. “Credible intel [intelligence] was received that JeM was planning more suicide attacks in India. In the face of imminent danger, a pre-emptive strike became absolutely necessary,” he said.

Indian Prime Minister Narendra Modi did not directly mention the air strikes when he addressed a political rally in Rajasthan later on Tuesday but he told cheering crowds: “I understand your enthusiasm and your energy. Today is a day we bow before our heroes.”

India is due to hold elections by the end of May.

Pakistan’s army spokesman Major General Asif Ghafoor said the strikes caused no casualties. He tweeted that Pakistani jets were scrambled and forced the Indian planes to make a “hasty withdrawal”, dropping their payload in an open area.
Pakistani Prime Minister Imran Khan later convened an urgent meeting of national security chiefs and condemned “irresponsible Indian policy”. “Once again [the] Indian government has resorted to a self-serving, reckless and fictitious claim,” a statement issued after the meeting said. “This action has been done for domestic consumption, being in an election environment, putting regional peace and stability at grave risk.”

Meanwhile, residents in several towns near Balakot reported hearing explosions early on Tuesday.

Mohammad Adil, a farmer in Jaba village, said he and his family were woken at about 03:00 by “a huge explosion”. “Then we heard jets flying over. We went to the place in the morning. There was a huge crater and four or five houses were destroyed,” he said. In Srinagar city, in Indian-administered Kashmir, residents expressed concerns over the spike in tensions.

“Whatever is happening between these two hostile neighbours, it’s us who are in the middle of this war theatre,” Shabir Aakhoon, a banker, said.

Local reporter Sameer Yasir says a heavy military build-up in the past three days has caused panic. Anticipating full-scale war, civilians have stockpiled food and crowded petrol pumps, triggering traffic jams in many places, he adds.

On 14 February, more than 40 Indian paramilitary police were killed in a militant operation in Indian-administered Kashmir. It was the deadliest attack on Indian forces in Kashmir for decades. The assault was claimed by Pakistan-based JeM, and prompted a spike in tensions.

Pakistan denied involvement, while India said its neighbour had had a “direct hand” in the attack, and accused it of providing sanctuary to the militants.

Both India and Pakistan claim all of Muslim-majority Kashmir, but control only parts of it. The nations have fought three wars and a limited conflict since independence from Britain in 1947 – and all but one were over Kashmir.

Pakistan’s Prime Minister Imran Khan said on Sunday his Indian counterpart Narendra Modi should “give peace a chance”. He added that if India provided “actionable intelligence” regarding the Pulwama attack that proved Pakistani involvement, “we will immediately act”.

On Saturday, Mr Modi had called on Mr Khan to join India in fighting poverty and illiteracy, instead of the pair fighting each other.
