A powerful rocket exploded late Wednesday in Afghanistan's capital, Kabul, near an area where the U.S. embassy and NATO peacekeeping headquarters are located.
Reports from the scene say a security guard was wounded in the blast.
In Washington, a U.S. State Department spokesman says the rocket hit or landed close to the Afghan Communications Ministry. The U.S. embassy and a base for NATO-led forces are nearby. NATO troops have sealed off the area.
U.S. officials say all U.S. embassy personnel are safe and accounted for.
A U.S. embassy spokesman told the Associated Press he could not confirm whether the diplomatic mission was the target of the blast. No one has claimed responsibility for the attack.
