Russia has evidence Turkish troops in Syria, Lavrov says
The comments by Lavrov are the latest confrontation between Moscow and Ankara, after Turkish jets shot down a Russian warplane near the Turkish-Syrian border in November.
"Turkey has started to declare it has a sovereign right to create some safety zones on Syrian territory," Lavrov told Russian television channel Ren-TV. "According to our data, they have already 'dug themselves in' several hundred meters from the border in Syria. ... It's a sort of creeping expansion."
Lavrov also said that Russia would insist the United Nations invites Kurds to peace talks on the Syrian conflict despite Turkey's opposition.
Lavrov added to Ren-TV that Russia was willing to coordinate its actions in Syria with the United States so that the city of Raqqa could be taken back.
"At some stage the Americans suggested carrying out a 'division of labor': Russia's air force should concentrate on freeing Palmyra and the U.S. coalition with Russian support should concentrate on freeing Raqqa."
