ISLAMABAD. Nov 10: Afghanistan's northern-based opposition accused their Taliban enemies Tuesday of violating a ceasefire and attacking their positions north of the beleaguered capital, reports AP.

However, they said It wouldn't effect an agreement between Afghanistan's two warring sides to continue with a prisoner exchange.

The Taliban launched an offensive in Dasht-i-Archi, a district in northern Kunduz province, some 250 kilometers (150 miles) north of Kabul and resorted to heavy artillery fire in the Ghorband area of central Parwan province, barely 60 kilometers (36 miles) from the capital, opposition spokesman who identified himself only as Arif said.

There was no immediate comment from the Taliban militia.

Opposition fighters repulsed the Taliban attack in Kunduz province, while in Parwan province they retaliated, he said.
