MUMBAI — At least 10 people have died and 33 injured after suspected militants fired on a bus carrying Hindu pilgrims in the Indian federal territory of Jammu and Kashmir, police officials said.

The driver lost control, causing the bus to plunge into a gorge in Reasi district of Jammu, they added.

While rescue operations have concluded, a search operation by the Indian army and police is under way to track down the attackers.

Officials said Prime Minister Narendra Modi had taken "stock of the situation" and asked for the best medical care to be provided to the injured.

"All those behind this heinous act will be punished soon," Manoj Sinha, the region's top administrator, wrote on X (formerly Twitter).

Officials say the bus was on its way to the base camp of the famous Hindu shrine of Mata Vaishno Devi when it was fired upon.

No one has claimed responsibility for the attack but Mohita Sharma, the district police chief, told Reuters that suspected militants had "ambushed the bus".

The Himalayan region of Kashmir has been a flashpoint between India and Pakistan for over six decades.

Since 1947, the nuclear-armed neighbors have fought two wars over the Muslim-majority territory, which both claim in full but control in part. Since 1989, Indian-administered Kashmir has also seen an armed insurgency against Delhi's rule, claiming thousands of lives.

Delhi accuses Islamabad of harboring militants and disrupting peace in the region, a charge Pakistan denies.

The news of Sunday's attack broke as Modi took oath as India's prime minister for the third consecutive term at a swearing-in ceremony in Delhi.

The passengers are yet to be identified but it is believed they are from the northern Indian state of Uttar Pradesh, Ms Sharma told a newspaper.

Photos showed some injured people, including a woman, being taken to a hospital in Jammu for treatment.

Amit Shah, who was home minister in Modi's previous government, expressed grief over the incident.

"The culprits of this dastardly attack will not be spared and will face the wrath of the law," he wrote on X, formerly Twitter.

Rahul Gandhi, the leader of main opposition party Congress, questioned the security situation in the region.

"This shameful incident is the true picture of the worrying security situation in Jammu and Kashmir," he wrote on X.

In 2017, seven Hindu pilgrims, six of them women, were killed after their bus, returning from the famed Amarnath pilgrimage site in Anantnag district, got caught in a gun battle between police and militants. — BBC
