MOSCOW, Feb. 2 (Xinhua) -- The first meeting of a joint task force on Syria involving experts from Russia, Turkey, Iran and the United Nations will be held on Monday in Astana, Kazakhstan, the Russian Defense Ministry said Thursday.

The meeting will discuss the implementation of the cease-fire regime, develop measures to suppress truce violations, enhance mutual trust between the Syrian government and the opposition, and solve humanitarian assistance issues, the ministry said in a statement.

The task force will pay special attention to the separation of the moderate opposition from the formations of the Nusra Front, which is considered by the three countries as a major problem for the Syrian cease-fire effective on Dec. 30, 2016, it said.

The Astana meeting will involve representatives from the Syrian government and the armed opposition, said the ministry.

The task force was launched at last week's Astana meeting on Syria.
