The United Nations Support Mission in Libya (UNSMIL) condemned the attack on the family of the prominent security commander Salah al-Marghani, killing him and his wife in front of their children.

The mission stressed in a statement Saturday, the need to end the gang-style targeted killings and enforced disappearances in Greater Tripoli.

"These crimes are in violation of International Humanitarian Law (IHL); perpetrators must be brought to justice," UNSMIL tweeted.
