Montenegro said someone threw an explosive device into the U.S. Embassy compound in Podgorica late Wednesday before blowing themselves up.
A government statement said the device was "most probably" a hand grenade, and several journalists who saw the site reported no damage.
U.S. State Department spokeswoman Heather Nauert said the embassy confirmed a small explosion near the compound and was working to confirm the safety of its staff. Nauert said embassy officials were also working with local police to identify the assailant.
Shortly after the incident, the embassy issued a security alert telling people to avoid the area.

美国国务院发言人诺尔特说,美国驻黑山大使馆证实,大使馆附近有一枚小型爆炸物,正在确认所有使馆人员是否安全。诺尔特说,美国大使馆的官员正在协助当地警方辨明攻击者的身份。
事件发生后,美国大使馆发布了一项安全警示,要人们避开大使馆所在地区。
