BELGRADE – Russian Foreign Minister Sergei Lavrov says Moscow has evidence that Turkish forces are on Syrian territory despite Ankara’s denial of troops’ entry to the war-torn Arab country.

Lavrov made the remarks in an interview with Ren-TV that was broadcasted on Sunday.

Last December, Moscow also said it has evidence Turkey is involved in the smuggling of oil from areas held by ISIS in Iraq and Syria. Ankara has strongly rejected the claim.

Turkish Defense Minister Ismet Yilmaz has rejected that Turkish forces have entered Syrian territory to help foreign-backed militants fighting against the Syrian government. Last month, Turkish Foreign Minister Mevlut Cavusoglu, however, said Saudi Arabia and his country could launch a ground operation in Syria.
