MOSCOW — Foreign Minister Adel Al-Jubeir on Tuesday poured cold water on Russian calls to join forces with the Syrian authorities against Daesh (the so-called IS) militants, insisting it was impossible to work with President Bashar Al-Assad. Moscow — one of Assad's few remaining allies — has called for coordination between the Syrian government and members of an international coalition fighting the extremist group, which controls swathes of territory in Syria and Iraq. But during his meeting with his Russian counterpart, Al-Jubeir insisted there would be no cooperation with the Syrian regime. “As for a coalition in which Saudi Arabia would participate with the government of Syria, then we need to exclude that. It is not part of our plans,” Jubeir said in comments translated into Russian. “Our position has not changed... there is no place for Assad in the future of Syria,” Jubeir said. “We think that Bashar Al-Assad is part of the problem, not part of the solution.” Saudi Arabia is already part of a US-led coalition that began an air campaign against Daesh in Syria last September. Russia supports Assad while Saudi Arabia insists he must quit to help end a four-year conflict that has cost over 240,000 lives. The two ministers last met in Qatar on Aug. 3 when Lavrov, Jubeir and US Secretary of State John Kerry held a three-way meeting, with Syria topping the agenda. Lavrov said Moscow was not looking to establish a formal alliance against the radical group but warned a failure to cooperate could open the door to the extremists. He admitted that there remained “persistent differences” between Riyadh and Moscow over how to tackle the Syrian conflict. “The exit of President Assad is part of these differences,” Lavrov said. He said Moscow would hold separate talks with Syrian opposition representatives including the Syrian National Coalition and Syrian Kurdish Democratic Union in coming days. The two ministers also discussed possible Saudi purchases of Russian arms in the context of a planned visit by the Saudi king to Russia. — Agencies
