Warplanes pounded strongholds of President Burhanuddin Rabbani's troops in Kabul on Thursday, while neighboring Pakistan shut its border to Afghans fleeing the factional fighting.
Warlord Rashid Dostum, who was a general for the communist regime ousted in 1992, sent his fighter pilots on repeated raids over Kabul for a second straight day. There was no immediate word on damage or casualties.Dostum lately has allied with Prime Minister Gulbuddin Hekmatyar's faction in an attempt to oust Rabbani, whose forces control most of the battered capital.
Rabbani's men have held their ground since the fighting erupted Jan. 1. The nearly nonstop battles have killed an estimated 400 people around Kabul and more than 4,000 have been wounded.
The bloodbath has sent tens of thousands of civilians fleeing Kabul. Most headed east toward the Pakistani border, 140 miles away, but refugees are now finding that traditional haven closed.
Pakistan said it no longer will allow all Afghans to cross.
