Libyan army commander Khalifa Haftar announced the start of military operations to “liberate” the city of Derna after his forces clashed with rival militias on the city’s outskirts.
“Zero hour for the liberation of Derna has struck. Our army forces are now targeting their hideouts,” Haftar said at a military parade in Benghazi.
“We have given instructions to avoid civilians,” he said. “Peace efforts in Derna have reached a dead end.”
Derna is the last major opposition to Haftar’s Libyan National Army (LNA) in eastern Libya. LNA has surrounded the city, on the coastal highway between Benghazi and Egypt and threatens to start land operations there.
Its campaign has so far been limited to encirclement with occasional air strikes and bombardments.
Derna is controlled by a coalition of Islamists and rebel veterans known as the Derna Mujahideen Shura Council (DMSC). Egypt, which backs the LNA, has also carried out air strikes in Derna against what it said were training camps sending militants into Egypt.
There were air strikes south-east of Derna on Sunday, followed by clashes on Monday around a flour factory east of the city. Four LNA troops were killed and five wounded, a field hospital doctor said. DMSC said one of its men was killed.
In recent weeks LNA has deployed new units in the Derna area and at the end of April, Haftar made a rare visit to forces outside the city, following his return from medical treatment in France.
After Libya split in 2014 between rival camps in the east and west of the country, Haftar gradually emerged as the dominant figure in the east. He is aligned with a parliament and government based in eastern Libya and opposes the internationally-recognised government in Tripoli.
On Monday he was attending a military parade in Benghazi to mark the fourth anniversary of the start of his “Dignity Operation”, the campaign in which the LNA battled Islamists and other rivals to take control of Benghazi last year.
The United Nations is leading efforts to stabilise Libya and prepare it for elections before year-end, but armed violence is still common across the country.
Another flashpoint is Sabha, where fighting between communal groups linked to the wider conflict escalated in recent weeks.
On Sunday, three children in Sabha were killed and five people wounded by shelling, the manager of Sabha Medical Centre said.
Before that, at least 18 people were killed and 86 wounded in fighting since February, he said. More shelling in residential areas was reported on Monday.
