"No US citizens are among the victims. The Indonesian government has described the incident as a terrorist attack," the statement said on Thursday.
Earlier in the day, at least 10 people were killed in a series of explosions in the downtown area Jakarta carried out by several assailants, who traveled on motorcycles, carrying rifles and explosives.
Following the attack, the embassy strongly condemned the explosions and said that the United States and Indonesia would continue to work together to "combat the shared threat of terrorism."
Jakarta's police say that Daesh militant group, which is prohibited in numerous countries, including Russia and the United States, was likely involved in the explosions.
