WASHINGTON - The United States has voiced its concern over clashes between Indian forces and protesters in India-held Kashmir and called for a peaceful resolution of the heightening tensions sweeping the disputed state.

"Obviously, we’re concerned about the violence," State Department Spokesman John Kirby said Monday when questioned about the killing of 30 civilians after protests demonstration followed the shooting of Kashmiri leader Burhan Wani by Indian troops on Friday.

"We encourage all sides to make efforts towards finding a peaceful resolution," Kirby said in what was seen as mild reaction to an enormous tragedy.

"This is really a matter for the Government of India to speak to specifically, and I’d refer you to them for more comment," he said even though Kashmir is an internationally recognised dispute.
