Seven police, including their commander, died when a suicide bomber detonated his explosives next to a group of officers in Logar province, south of Kabul.
"A suicide attacker on foot this morning targeted an Afghan local police commander in Puli Alam, killing him and six others," Abdul Hakim Eshaqzai, Logar's provincial police chief, told AFP.
The attacker, who was wearing a military uniform, struck as the commander was arriving at his office for a meeting.
Also today, a remote-controlled bomb hit a police car in Jalalabad city in the east of Afghanistan, killing three police, Ahmad Zia Abdulzai, the provincial spokesman told AFP.
Another roadside bomb blast left two civilians wounded in the capital Kabul.
The Taliban, who claimed responsibility for the Logar and Jalalabad attacks, have stepped up attacks as the withdrawing NATO-led forces leave Afghan security forces to fight the insurgents on their own.
This year alone more than 4,600 Afghan soldiers and police have been killed in combat, a top US commander said last week, describing the losses as "not sustainable in the long term."
Today, a suicide bomber walked into the offices of Kabul's police chief and detonated his explosives, killing a senior aide.
