APMINGORA, Pakistan – Taliban militants blocked roads with rocks and trees, preventing terrified civilians from fleeing a Pakistani valley Thursday as the army stepped up a ground and air assault on the guerrillas that has been applauded by the U.S., witnesses said.
Destabilizing violence is flaring in Pakistan just as its embattled president is appealing in Washington for more help to reverse the extension of Taliban-held territory to within 60 miles (100 kilometers) of the capital. The U.S. is particularly concerned by the unrest because its troops are fighting an increasingly virulent insurgency in Afghanistan fed from militant havens in Pakistan's lawless border area.
Officials are bracing for a mass exodus from the Swat Valley, a former tourist destination where fighting has resumed after the breakdown of a controversial peace deal earlier this week. The military claimed to have killed more than 80 militants in the region on Wednesday. There has been no official word on civilian casualties.
More than 500,000 Pakistanis driven out by fighting in other regions of the northwest are already living in makeshift camps or with relatives, adding a growing humanitarian crisis to the country's daunting security, economic and political problems.
