Four Afghan policemen have been killed in a night-time attack by the Taliban on a security outpost in the country's west, an Afghan official said.
Police chief Sharafuddin Sharaf said the attack happened in the Bla Murghab district of Badghis province.
He said the Taliban tried to storm the security outpost, triggering a three-hour gun battle and killing four members of the local police force. Three other policemen were injured.
The attack was the latest in a wave of violence across Afghanistan as the Taliban intensify their campaign ahead of the US-led foreign forces' withdrawal from the country in 2014.
