Rattled by a shooting attack on its embassy in Libya, South Korea will convene an interagency meeting Monday to assess the situation and discuss ways to protect its nationals there, an official said.

Gunmen opened fire on the embassy in the Libyan capital of Tripoli on Sunday, killing two local security guards and wounding another. There were no South Korean casualties.

Militants claiming to be affiliated with the Islamic State said they were behind the attack.

"The government plans to hold a meeting of relevant authorities in the afternoon today to discuss security measures for the around 30 South Korean nationals staying in Libya," the official said.

Deputy Minister for Overseas Koreans Lee Key-cheol will preside over the meeting.

South Korea is considering transferring its two diplomats and one embassy staffer in Tripoli to Tunisia, where a temporary office is located.

South Korean officials are trying to confirm whether the assailants directly targeted South Koreans. (Yonhap)
