Afghan officials say two roadside bomb blasts in the southern city of Kandahar have killed at least seven policemen and wounded several others.
Officials say the first explosion Thursday, destroyed a vehicle carrying four Afghan police, killing the officers. As police arrived to carry away the bodies, a second bomb went off nearby, killing three more officers and wounding a journalist.
Authorities say the bombs appear to have been detonated by remote control.
In another development, the U.S. military says a commander who led airstrikes against the Taleban last month acted correctly in an operation that Afghan officials say killed about 50 civilians.
The military says the U.S. commander used the "appropriate level of force" in the fighting in the western town of Shindand in Herat province. The U.S. military says all targets were identified as hostile or had been under observation at the time.
The U.S.-led coalition in Afghanistan says more than 130 Taleban insurgents - not civilians - were killed in the operation and another major battle in Herat.
Wednesday, Afghan President Hamid Karzai visited western Afghanistan to meet with families of people killed in the U.S. airstrikes.
