The Pakistani Foreign Office says it has protested formally to India for an attack on its army post.

A statement issued by the office Monday says the Indian deputy high commissioner was summoned to the foreign ministry over what Pakistan calls an "unprovoked" attack on an army post Sunday.

The mostly-Muslim mountainous Kashmir has been a flashpoint of violence between these two neighbors, who have fought two full-scale wars over control of the region.

Pakistan and India traded accusations Sunday of violating the cease-fire in the disputed northern Kashmir region.

Islamabad accused Indian troops of a cross-border raid that killed one of its soldiers. The statement warned India to avoid a recurrence of such incidents.

India denied the raid and said Pakistani shelling destroyed a home on its side.
