Pakistan's Prime Minister Nawaz Sharif is meeting with army chiefs and advisers over clashes this week between Pakistani and Indian troops along the border in disputed Kashmir that have killed at least 19 civilians on both sides.

The flare-up is the most serious violation of a 2003 cease-fire accord between India and Pakistan.

Sharif told the National Security Committee that he convened the meeting Friday in the capital, Islamabad, to discuss "tensions" along the so-called "Line of Control" in the disputed Himalayan region. Hs remarks were carried on Pakistani state television.

The fighting erupted on Sunday as Muslims in the region were preparing to celebrate the key Islamic holiday of Eid al-Adha. Since then, thousands have been displaced. The mortar-and-gunfire exchanges have also killed 11 Pakistani and eight Indian villagers.
