Libyan commander Khalifa Haftar announced the start of military operations to “liberate” Derna on Monday after his forces clashed with rivals on the outskirts of the eastern city.
“Zero hour for the liberation of Derna has struck. Our army forces are now targeting their hideouts,” Mr Haftar said in a speech at a military parade in Benghazi.
“We have given instructions to avoid civilians,” he said. “The peace efforts in Derna have reached a dead end.”
Derna is the last major bastion of opposition to Haftar’s Libyan National Army in the east of the country.
