Two militants on a motorbike blew themselves up outside the U.S. Embassy in Tunisia on Friday, killing a policeman and injuring several others in the country’s most serious attack in months. The explosion took place near the embassy’s main gate, where a Reuters journalist saw a scorched, damaged motorbike and a damaged police vehicle lying amid debris as police gathered around and a helicopter whirled overhead. The Interior Ministry said two militants were killed carrying out the attack and five police officers were injured, while a civilian suffered minor injuries. State news agency TAP reported that one policeman was killed.

The U.S. Embassy in a tweet urged people to avoid the area. Roads around security installations were closed in some parts of the capital and some international institutions were put on lockdown or evacuated.
