A top military official says Russia has halted all airstrikes in areas of Syria where armed groups, including government forces, said they would abide by a cease-fire.

"The Russian Federation has completely stopped attacks in the 'green zone', that is to say those areas and armed units that have sent to us requests for cease-fire," Maj. Gen. Sergei Rudskoy said Saturday at a briefing in Moscow.

He said 17 armed groups have said they would abide by the cease-fire.
