More than 80 people, mostly anti-government militants, have been killed across Afghanistan in fightings over the past 24 hours, officials said Friday.

More than a dozen militants have been confirmed dead as government forces increased pressure on the armed opposition groups in Afghanistan, officials said Monday.

A clash between government forces and the Taliban fighters has left four local police and three militants dead in Khawja Ghar district of Afghanistan's northern Takhar province on Sunday, district governor Mohammad Omar confirmed.

 Fighting has intensified in northern Afghanistan as 21 fighters from warring sides were killed in clashes between the government forces and Taliban militants in two northern provinces over the past two days.
