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.

黑山共和國說，有人星期三晚上在首都波德戈里察向美國大使館院內扔了一枚爆炸裝置，然后把自己炸死。

黑山共和國政府的一份聲明說，這個爆炸裝置很可能是手榴彈。一些到現場采訪的記者報道說，爆炸沒有造成任何損失。

美國國務院發言人諾爾特說，美國駐黑山大使館證實，大使館附近有一枚小型爆炸物，正在確認所有使館人員是否安全。諾爾特說，美國大使館的官員正在協助當地警方辨明攻擊者的身份。

事件發生后，美國大使館發布了一項安全警示，要人們避開大使館所在地區。
