The UN envoy to Libya, Ghassan Salame said that Haftar's threats to arrest the head of the Presidential Council (PC), Fayez Al-Sarraj, seems more like a coup than a counter-terrorism operation.

"What Haftar is doing now, does not fall necessarily under the fight against terrorism; it is an attempt to control Tripoli," Salame told BBC radio.

Spokesman for the self-styled army of Haftar, Ahmed al-Mismari announced earlier the issuance of arrest warrants against military and civilian figures, among them is the PC's head, besides other senior figures.
