The press service also noted that "the two leaders called for further strengthening of cooperation in combating terrorism and pointed out in particular that the truce does not apply to terrorist groups, above all, Islamic State."
Putin and Erdogan also "discussed some other pressing issues of bilateral relations."

According to Putin, three documents have been signed. The first document was signed by the Syrian government and armed opposition on the cessation of hostilities in Syria. The second document is a package of measures to monitor the ceasefire, while the third one is the statement of readiness to start peace talks on the Syrian settlement, the president noted.
