Pakistan expects 500,000 to flee Taliban fighting

MINGORA, Pakistan – Black-turbaned militants roamed city streets and seized buildings in a northwestern Pakistan valley Tuesday as thousands of people fled fighting between the Taliban and troops that the government said could lead to an exodus of half a million people. The Taliban declared the end of their peace deal with the government

A witness in Mingora told an Associated Press reporter that black-turbaned militants were deployed on most streets and on high buildings, and security forces were barricaded in their bases. Another reported heavy gunfire for much of the day. Both asked for anonymity out of fear for their life.

Pakistan has waged several offensives in the border region in recent years that have often ended inconclusively amid public anger at civilian casualties. The country's army, trained to fight conventional battles against rival India, is not used to guerrilla warfare.

Washington has called for tougher action, and U.S. officials said Obama would seek assurances fromPresident Asif Ali Zardari that his country's nuclear arsenal was safe and that the military intended to face down extremists in coordination with Afghanistan and the United States.

Buses carrying the residents of Mingora, the region's main town, were crammed inside and out: Refugees clambered onto the roofs after seats and floors filled up. Children and adults alike carried their belongings on their heads and backs — all of them fleeing fighting they fear is about to consume the region.
