US President Donald Trump called for a "rapid de-escalation" of the Libyan conflict on a call with his Turkish counterpart, Recep Tayyip Erdogan, on Saturday, the White House said. White House spokesman Judd Deere said in a statement: "President Trump reiterated concern over worsening foreign interference in Libya and the need for rapid de-escalation." Trump and Erdogan also discussed the situation in Syria. They "reaffirmed the urgent need for a political resolution to the conflict in Syria, as well as unimpeded humanitarian access throughout the country,” said Deere. The phone conversation between the US and Turkish presidents came as forces loyal to the Government of National Accord led by Fayez al-Sarraj, backed by Turkey, said Saturday they seized three barracks from the Libyan National Army of Khalifa Haftar, south of the capital Tripoli. "Our forces have regained control of the Yarmouk, Hamza and Al-Sawarikh camps," said Mohamad Gnounou, spokesman for the GNA. Haftar called on his forces to rally against Turkey. In an audio message addressed to his forces, he urged them to battle the "colonial" intervention by Turkey until its defeat. "You are creating glory while fighting the odious colonizer greedy for our wealth," he said. "And you are waging war on all fronts, a war in which there is nothing but victory."
