Three police officers have died and others have been injured in the violence, police said. The Afghan Public Health ministry said one civilian was killed and at least 18 were wounded but none seriously.
Taliban spokesman Zabiullah Mujahid told CNN that his group targeted "the U.S. Embassy, governmental organizations and other foreign organizations."
The strike occurred amid intelligence that insurgents might launch a high-profile attack in the capital around the 10th anniversary of the September 11, 2001, terrorist attacks against the United States, a coalition officer and a senior ISAF official confirmed to CNN.
