Syria Cease-Fire Focus of US, European Diplomatic Talks in London by VOA News The top U.S. diplomat is meeting with Washington's European allies in London Sunday to discuss Syria. John Kerry is meeting with the group to brainstorm ideas about ending the Syrian conflict, now in its sixth year. He said a meeting in Switzerland with his Russian counterpart, Sergei Lavrov, and several Middle Eastern countries Saturday had produced "several ideas that need to be quickly followed up," but he did not elaborate. The talks in Lausanne opened less than two weeks after Washington suspended bilateral talks with Moscow following the collapse of a shaky cease-fire in the divided city of Aleppo. Kerry told reporters that negotiators were "working very hard" to reach a cease-fire agreement in the war-torn city. The United States and its coalition partners accuse the Syrian government of President Bashar al-Assad and his Russian allies of a deadly and indiscriminate bombing campaign in rebel-held eastern Aleppo. Monitors say Russian and Syrian airstrikes and artillery have killed hundreds of civilians in the city and cut off more than 250,000 others from critically needed supplies since September. For its part, Russian diplomats insist the strikes are targeting extremists. They have repeatedly blamed Washington for failing to separate extremist fighters from the larger rebel fighting force and from the city's civilian population. On Saturday, Syrian opposition forces backed by Turkish airstrikes and armor launched an offensive in northern Syria to wrest control of a key border town from Islamic State extremists. Dabiq, 10 kilometers from the Turkish border, is cited in apocalyptic Sunni prophecy as the site of an end-of-times battle between Muslims and their "Roman" enemies. Islamic State named its online magazine after the town in 2014. Monitors from the Britain-based Syrian Observatory for Human Rights said the force seized several strategic areas near the town Saturday. Heavy shelling was reported as the force prepared for battle less than two kilometers from the center of the fortified town. Turkey launched unprecedented cross-border strikes against IS strongholds on August 24, just days after linking IS fighters to a suicide bombing at a wedding in the nearby Turkish city of Gaziantep that killed 51 people. At the time, Turkish Foreign Minister Mevlut Cavusoglu said the Syrian frontier must be "completely cleansed" of Islamic State. Turkish President Recep Tayyip Erdogan vowed Saturday to declare "a terror-free safe zone of 5,000 [square] kilometers," a border area that would include territory already captured in the offensive.
