Taliban rebels ambushed a police convoy in western Afghanistan killing a district police chief and five others, and wounding three other policemen, police said on Friday.
Mohammad Sediq, police chief of Adraskan district of Herat province was visiting police posts in the area on Thursday when his convoy came under attack, Herat province's police chief, Nisar Ahmad Paikar, told the agency.
Paikar blamed the attack on remnants of Taliban who have waged an insurgency since 2001 when they were forced out of power by US-led invasion of Afghanistan.
In another incident US-led coalition troops raided a Taliban cell in remote eastern Nuristan province near the Pakistan border on Wednesday, killing four insurgents and arresting two, provincial police chief Abdul Ghani said.
There are about 8,000 coalition soldiers with a separate 31,000-strong NATO-led force trying to bring stability to the volatile country.
The almost daily violence in Afghanistan is also blamed on the Al-Qaeda network and a radical faction led by fugitive ex-prime minister and fundamentalist Gulbuddin Hekmatyar.
