A suicide car bomber rammed the car of the governor of Kandahar province Thursday, damagingAsadullah Khalid'swhite SUV, the Associated Press reports.

It was not immediately clear whether Khalid was in the vehicle or there were any casualties besides the bomber.

The attack came hours after two bombs planted by Taliban fighters detonated in Kandahar City on Thursday morning, exploding within 15 minutes of one another. The co-ordinated attacks killed as many as seven people, including Afghan police officers.

The first device to explode — a remote-controlled bomb — targeted a police vehicle and killed four officers, said police official Gul Zaman. Witnesses said the police car had been driving through the Kandahar streets at the time, and the force of the blast hurled the bodies of the officers from the vehicle.

As police raced to the scene of the wreckage, the second blast went off about 15 minutes later, killing an additionalthree police officers and wounding five, Zaman said. Two camera operators were also reportedly wounded.

The Taliban claimed responsibility for the co-ordinated double attacks, which come less than a week after NATO and Afghan forces killed a senior Taliban military field commander during a U.S.-led operation in Helmand province.

"First we set off a remote control explosion on a police vehicle, then we were waiting for the police to arrive on the scene, then we did a second blast," Qari Yousef Ahmadi, a purported Taliban spokesman, said by satellite phone from an undisclosed location.

Double bombingsrare in Afghanistan

The double-attack style is considered a rare tactic by Taliban in Afghanistan, more often used by insurgents in Iraq.

Since the death of TalibanMaj. Mullah Dadullah, Taliban have warned of "bad consequences" if the Afghan government did not hand over Dadullah'sbody to his relatives.

The U.S. general in charge of NATO troops in Afghanistan also said troops were anticipating a violent backlash following Dadullah's death.

Gen. Dan McNeill told a British newspaper he expects militants will intensify their attacks using suicide bombs against foreign troops and Afghan civilians.

About 1,800 people have been killed in insurgency-related violence this year, according to an Associated Press count based on U.S., NATO and Afghan officials.
