Eleven people were wounded in the Afghan capital of Kabul early Tuesday when a bicycle bomb was detonated by remote control near a police bus.
The morning blast injured police and civilians, Abdul Rahman Sarjang, a police officer, told the Associated Press at the scene.
Afghan police sifted through the remains of the bicycle bomb, which shattered windows on the bus but did not severely damage it. Police were able to drive it away about an hour after the attack.
"They are targeting police," said Jan Agha, a police officer at the scene.
