Libyan renegade military commander Khalifa Haftar has backed a ceasefire in Libya to take effect from Monday, Egypt's president announced after talks in Cairo.
The development follows a series of military victories of Libya's UN-recognised Government of National Accord (GNA) against Haftar's forces.More: Has Khalifa Haftar's campaign in Libya failed?

"This initiative calls for respecting all international efforts and initiatives by declaring a ceasefire from 6pm [16:00 GMT] Monday, June 8, 2020," President Abdel Fattah el-Sisi told a news conference on Saturday.
He was speaking alongside Haftar and his ally, eastern parliament speaker Aguila Saleh.
El-Sisi urged international support for the initiative and called on the United Nations to invite Libya's rival administrations for talks.
The initiative, called the "Cairo declaration", urged the withdrawal of "foreign mercenaries from all Libyan territory", he said.
El-Sisi added that the declaration also called for "dismantling militias and handing over their weaponry so that Libyan National Army [led by Haftar] would be able to carry out its military and security responsibilities and duties".
The Egyptian president also said the initiative paves the way for forming an elected presidential council in Libya.
He added that it prevents "extremist militias" from gaining control over the country's resources.Sirte offensive
Meanwhile, forces loyal to Libya's UN-recognised government said they launched an offensive on Saturday to seize the strategic city of Sirte.
"The air force has carried out five strikes in the outskirts of Sirte," slain dictator Moamer Kadhafi's hometown and the last major settlement before the traditional boundary between Libya's west and east, GNA spokesman Mohamad Gnounou said.
"Orders have been given to our forces to begin their advance and to systematically attack all rebel positions," he added.
Sirte was taken by Haftar's forces virtually without a fight in January after one of Libya's myriad local fighters switched sides.
Libya plunged into chaos in 2011 when an uprising toppled and later killed longtime leader Muammar Gaddafi.
It is split between two rival administrations in the east and the west, each backed by opposing fighters struggling for power.
Haftar has since last year sought to regain control over the west, fighting the GNA in an abortive attempt to seize the capital Tripoli.
His LNA forces have in recent weeks lost crucial ground to GNA forces, which are backed by Turkey.
The GNA recaptured the strategic town of Bani Walid in the country's northwest from the LNA earlier on Saturday.
The latest development comes a day after the GNA seized the city of Tarhuna, Haftar's last stronghold in northwestern Libya, which was used as the main launchpad against Tripoli.
Friday's defeat inflicts serious blows to Haftar's 14-month offensive to capture Tripoli.
Haftar is supported by Egypt and the United Arab Emirates as well as Russia.
