In southern Afghanistan, two police officers were killed and eight others wounded in a roadside bomb attack, while a NATO soldier from Canada died and three were hurt in a traffic accident.
Afghan officials say the bomb struck a vehicle carrying the officers in the Mianashin district of Kandahar province.
A spokesman for the Kandahar governor's office said the district chief (Shadi Khan) was also in the vehicle, but he escaped the attack unharmed. The spokesman blamed Taleban insurgents for the blast.
In a separate incident in the same province, one Canadian NATO soldier died and three others were injured in a traffic accident outside Kandahar city. NATO said the accident was not the result of hostile action.
Afghanistan is experiencing its deadliest phase of violence since the U.S.-led coalition ousted the Taleban government in 2001.
NATO took over security operations from U.S.-led coalition forces earlier this week in six southern Afghan provinces.
