Libya’s UN-backed government says 21 people have been killed and 27 wounded as Gen. Khalif Haftar’s army advances on Tripoli with the aim of capturing the capital. US and other international powers are evacuating personnel from Libya. US Secretary of State Mike Pompeo called for an immediate halt in fighting and talks to start. Prime Minister Fayez al-Serraj accused Haftar of attempting a coup and vowed to face him with force. Gen Haftar’s forces said they had lost 14 fighters, but had captured Tripoli airport which has not functioned for five years. His Libyan National Army, which controls eastern Libya, is backed by Egypt, the UAE, France and Russia.
