Insurgents including a suicide car bomber attacked the U.S. consulate in the western Afghanistan city of Herat on Friday, police said, and a gun battle was under way.
An Afghan translator was killed, while several other people, including police, were wounded.
It was unclear whether insurgents had made it inside the consulate building in relatively peaceful Herat, the main city in Afghanistan's west near the Iranian border. Some media reported up to seven people had been wounded.
The Taliban claimed responsibility for the attack, which underscored the perilous security situation in Afghanistan, where U.S.-led troops are reducing their presence ahead of a full withdrawal planned for next year.
The insurgent strikes are no longer concentrated in the country's south and east, but occur with troubling frequency in the north and west, which have been the more peaceful areas in years past.
