Heavily armed gunmen in suicide vests have detonated a truck bomb outside the US consulate in the Afghan city of Herat, sparking a shootout with American forces, officials say.
US State Department deputy spokeswoman Marie Harf said there were no American casualties and the US embassy in Kabul confirmed on Twitter that all consulate staff were safe after the attack early on Friday.
Afghan officials said at least one person had been killed and 18 others wounded.
The Taliban claimed responsibility for the attack, saying there were several casualties on the Afghan and US side, but the militia is known to exaggerate its claims of deaths and injuries.
The front gate of the US consulate was "extensively" damaged, Harf told reporters.
