"Of course, reaching a ceasefire as soon as possible is highly desirable. We also would like to see humanitarian corridors created all across Syria to solve humanitarian problems," Jarba said at a meeting with Russian Foreign Minister Sergei Lavrov in Moscow.
The leader of the opposition bloc underscored that the situation in Syria was deteriorating and Russia's contribution to the solution was valuable.
A ceasefire deal for Syria was worked out by Russia and the United States and took effect on February 27. The cessation of hostilities does not apply to terrorist organizations, such as Daesh and the Nusra Front, both of which are outlawed in many countries including Russia.
