German Chancellor Angela Merkel said Friday that officials are looking into the possibility of a four-way meeting on Syria involving Turkey, Russia, Germany and France. The idea of such a meeting has been raised by Turkey, AP reported. Asked about the possibility, Merkel said that there are already two main formats for talks on Syria, both working closely with UN Syria envoy Staffan de Mistura. “Nevertheless, a meeting between Germany, France, Turkey and Russia could make sense - this must be well-prepared, so there is no date yet,” the chancellor said. She added that leaders’ advisors will do preparatory work to decide whether it’s worth holding such a meeting. Syria is likely to be on the agenda when Merkel meets Russian President Vladimir Putin in Germany on Saturday.
