U.N. Special Envoy for Syria Geir Pedersen said on Monday that he would meet Russian, Turkish and Iranian foreign ministers in Geneva on Tuesday, a day before the first meeting of Syria's Constitutional Committee.

Turkey's Mevlut Cavusoglu, Iran's Mohammad Javad Zarif and Russia's Sergei Lavrov are due to meet in the Swiss city before the 150-member Syrian panel convenes under U.N. auspices.

Pedersen said: "We do believe that the fighting going on is just another proof of the importance to get a serious political process under way that can help sorting out the problems in all of Syria, including the northeast and also Idlib." (ILKHA)
