India has stepped up security in the occupied Jammu and Kashmir region because of an increase in “militant attacks” in the run-up to a G20 meeting on tourism in the Himalayan territory, officials said on Wednesday.

The city of Srinagar, the summer capital of the federal territory, is due to host a tourism working group meeting of G20 members on May 22-24, part of a series of meetings ahead of a G20 summit in New Delhi in September.

Suspected militants have stepped up attacks this year in the occupied region, across the mountains from the Kashmir Valley where Srinagar is located.

Ten soldiers and seven civilians have been killed in four attacks in the held region this year.

Security officials said they fear the “separatist militants” could try to promote their cause with an attack before or during the G20 meeting.

“The timing of these attacks is worrisome as they are planned just before the G20 meeting,” said a senior Indian army officer in the region. He declined to be identified as he is not authorised to speak to media.

Military and police officers said they had intelligence information that “militants” might target a military-run school in Indian Illegally Jammu and Kashmir and take students hostage.

In response, such schools had been shut and classes moved online until after the G20 meeting, they said.

Security agencies are not taking any chances in Srinagar, officers said.

Vijay Kumar, chief of police in the occupied valley, told Reuters that commandos had been deployed in the city and members of a counter-terrorism force would be on stationed in various places.

Srinagar has been at the centre of the insurgency against Indian rule since 1989.

Tens of thousands of people have been killed although the violence has been reduced in recent years.

India blames Pakistan for supporting the suspected insurgents. Pakistan denies that and accuses India of violating the rights of Kashmir’s Muslim people. India denies that.

The nuclear-armed neighbours, who have fought three wars, two of them over Kashmir, both claim the region in full but rule it in part.
