India lodged a formal protest with Pakistan on Wednesday over an incident in the disputed territory of Kashmir that left two Indian soldiers dead, but Islamabad denied any wrongdoing and called for a U.N. investigation.

"Regular Pakistan troops crossed the Line of Control ... and engaged the Indian troops who were patrolling the sector," India's foreign ministry said after the Pakistani envoy in New Delhi was summoned.

"Two Indian soldiers were killed in the attack and their bodies subjected to barbaric and inhuman mutilation," the ministry said in a statement, demanding that Pakistan ensure that nothing similar happens again.

The Line of Control, or LoC, divides the Indian and Pakistani portions of Kashmir, a Muslim-majority region whose then-ruler declined to join Pakistan, founded as a state for Muslims, when the subcontinent was partitioned in 1947.

Pakistan, along with many Kashmiris, calls on India to comply with a 1948 U.N. resolution urging that residents be allowed to vote to determine the region's status.

In Islamabad, Pakistan's foreign ministry cited an account from the military denying that any incursion took place and dismissed the Indian accusations as "unfounded."

Pakistan remains committed to the 2003 accord that established a cease-fire along the LoC, the foreign ministry said.

The two nuclear-armed neighbors have waged three wars over Kashmir and were seemingly on the verge of a fourth in 1999 after a sustained Pakistani incursion into Indian territory. EFE
