The capital of Afghanistan's northeastern Kunar province has fallen to Moslem guerrillas, bringing to four the provincial capitals now being held by the Afghan resistance, a guerrilla spokesman said.

Asim Nasser-Zia, a member of one of the moderate guerrilla organizations, said news of Asadabad's fall reached the Pakistan capital early Tuesday.The city had been under heavy seige for much of the past month. Details of the capture were sketchy, he said.

Fazle Akbar, a spokesman with the Afghan Information and Documentation Center in Pakistan's northwest frontier city of Peshawar, said government troops had begun evacuating Asadabad last week.
