Eight police officers have been killed by a roadside bomb in southern Afghanistan, Afghan police have said.
The blast happened on the outskirts of Kandahar, about 450km (280 miles) south-west of the capital, Kabul.
Several other officers were wounded in the attack, the police said.
Violence has surged in Afghanistan in recent weeks and Afghan and international troops are regularly targeted by Taleban insurgents.
Across Afghanistan, bloodshed has returned to levels not seen since the fall of the former Taleban regime in 2001.
About 4,000 people were killed in violence in Afghanistan last year.
