Pakistan summoned a senior Indian diplomat to its foreign ministry on Monday to condemn the weekend's cross-border fire that killed one Pakistani soldier and wounded another.
Gopal Bagley, the deputy High Commissioner of India in Pakistan, was handed a "protest note on the unprovoked Indian attack," the foreign ministry said in a statement.
"The Indian government was strongly urged to take appropriate measures to avoid recurrence of such incidents in future," the ministry said.
Islamabad alleges that Indian forces violated the border ceasefire agreement on Sunday by attacking and raiding a checkpoint in the disputed Himalayan region of Kashmir.
India rejected the accusation and said Pakistani forces incited the clash with "unprovoked firing" at their positions, which also destroyed at least one civilian home located nearby.
The two nuclear-armed rivals have fought two wars over Kashmir since their independence in 1947 from the British rule. Both countries claim the region, and each controls parts of it.
The two sides agreed on a ceasefire in 2003 but often accuse each other of violations.
