Afghan officials say militants have ambushed a checkpoint in the country's south, killing seven police officers.
The attack took place late Tuesday in Uruzgan province.
Provincial Governor Haji Khudai Rahim said a police officer who was at the checkpoint was involved in plotting the ambush.
In the country's east, police say a suicide car bomber killed a police officer and wounded four other people in Khost province on Wednesday. The Taliban claimed responsibility for the attack.
And NATO says two of its service members were killed in separate insurgent attacks Wednesday, one in the the south and the other in the east. The coalition did not provide further details.
NATO also said Wednesday that insurgents were responsible for the deaths of more than 100 Afghan civilians last month and more than 200 civilian injuries, despite the Taliban's claims that it has protected ordinary citizens.
The coalition also outlined four main ways that the Taliban bullies civilians, including indiscriminate violence, oppressive practices, imposing extremist ideology and preventing the growth and development of basic services.
The statement comes as coalition forces push to crack down on militants in Afghanistan, particularly in the country's volatile south.
