At least 15 people were killed, including women and children, in airstrikes on the eastern Libyan city of Derna late on Monday night, said a medical source.
The National Libyan Army has been besieging the city for months and has carried out intermittent airstrikes against it.
Military officials refused to comment on the latest strikes.
A resident of the city said that the shelling last about an hour and that they targeted the al-Dhahr al-Hamr neighborhood in southern Derna and the mountainous al-Fatayeh region, 20 kms away from the city.
The medical source said that at least 17 people were wounding in the strikes, adding that so far all victims were civilians.
The coastal city of Derna lies 265 kms away from the Egyptian border in the west. It is currently under the control of an alliance of extremists and former members of the “Shura Council of the Derna Mujahideen”.
The ISIS terrorist group captured ISIS in late 2014, but the Council managed to expel it in the following year.
