Russian warplanes leave Syria, raising U.N. hopes for peace talks

Russian warplanes flew home from Syria on Tuesday as Moscow started to withdraw forces from Syria

Russian warplanes flew home from Syria on Tuesday as Moscow started to withdraw forces that have tipped the war President Bashar al-Assad's way, and the U.N. envoy said he hoped the move would help peace talks in Geneva.

As the first aircraft touched down in Russia, U.N. envoy Staffan de Mistura called President Vladimir Putin's surprise move a "significant development" toward resolving a conflict which this week passes its fifth anniversary.

Assad's opponents hope Putin's announcement on Monday that most Russian forces would be withdrawn signaled a shift in his support. However, its full significance is not yet clear: Russia is keeping an air base and undeclared number of forces in Syria.

Russian jets were in action against Islamic State on Tuesday. Assad also still enjoys military backing from Iran, which has sent forces to Syria along with Lebanon's Hezbollah.

Russia said last month Assad was out of step with its diplomacy, prompting speculation Putin is pushing him to be more flexible at the Geneva talks, where his government has ruled out discussion of the presidency or a negotiated transfer of power.

Damascus has dismissed any talk of differences with its ally and says the planned withdrawal was coordinated and the result of army gains on the ground.

British Foreign Secretary Philip Hammond, whose government supports the opposition, indicated the gaps in Western understanding of Putin, saying he had "no insight at all into Russia's strategy" after a decision that came out of the blue.

The West had been equally surprised by Putin's decision to intervene. "Unfortunately none of us knows what the intent of Mr Putin is when he carries out any action, which is why he is a very difficult partner in any situation like this," Hammond said.

Analysts in Moscow said Putin's acquisition of a seat at the diplomatic top table may have motivated his move to scale back his costly Syria campaign.

"MOMENT OF TRUTH"

Russia appeared to be following through on its pledge, the U.S. White House said, but spokesman Josh Earnest said it was too early to assess the broader implications, adding Moscow did not give the United States direct notice of its withdrawal plan.

U.S. Secretary of State John Kerry welcomed Putin's announcement and said he planned to visit Moscow next week for what he called the best opportunity in years to end the war.

The Geneva talks are part of a diplomatic push launched with U.S.-Russian support to end a conflict that has killed more than 250,000 people, created the world's worst refugee crisis, and allowed for the rise of Islamic State. Opening the indirect talks, de Mistura said Syria faced a "moment of truth".

U.S.-Russian cooperation has already brought about a lull in the war via a "cessation of hostilities agreement", though many violations have been reported.

Opposition negotiators demanded on Tuesday that the government spell out its thoughts about a political transition in Syria, saying there had been no progress on freeing detainees, who were being executed at a rate of 50 a day.

The opposition High Negotiations Committee (HNC) used their first meeting in the round of peace talks to give de Mistura a set of general principles to guide the transition.

A peace process for Syria endorsed by the U.N. Security Council in December calls for a Syrian-led process that establishes "credible, inclusive and non-sectarian governance", a new constitution, and free, fair elections within 18 months.

The HNC wants Assad out of power by the start of a transition. While some rebels have expressed guarded optimism at Putin's announcement, others doubt he is about to put serious pressure on Assad.

"We do not trust them," said Fadi Ahmad of the First Coastal Division, who says his rebel group has been fighting a Russian-backed government offensive near the Turkish border throughout the cessation agreement that came into effect on Feb. 27.
