The Kremlin rebuffed criticism from the U.S. President Donald Trump on the military action in Idlib, Syria.
A Russian official said Syria’s Idlib province was held by rebels and militants were using it as a base to launch attacks against civilian and military targets.
He said, rebel attacks being launched from there needed to stop and free of all heavy weapons and jihadist fighters.
He said, Moscow would continue to back Syrian government offensive there.
The Syrian offensive has strained an agreement reached between Russia and Turkey for a demilitarized zone in Idlib.
The Russian and Syrian military forces are jointly bombing Idlib and rebel control areas.
Trump on Sunday urged Russian and Syrian government forces to stop bombing Idlib.
The assault has created a humanitarian crisis, more than 200,000 people fled since strikes began at the end of April.
