U.S. Secretary of State John Kerry is in Geneva to hear Russia's plan to eliminate Syria's chemical weapons.

The plan would avert a proposed U.S. strike on Syria but Western powers remain skeptical.

British Foreign Secretary William Hague:

SOUNDBITE: BRITISH FOREIGN SECRETARY WILLIAM HAGUE SAYING:

"Given their track record any commitment made by the Syrian regime must be treated with great caution….The House should be in no doubt of the scale of the challenge and immense practical difficulties that would need to be overcome."

In Turkey, where warplanes are on alert against possible threats from neighboring Syria, the language is less subtle.

Prime Minister Tayyip Erdogan says Assad is only buying time.

SOUNDBITE: TURKISH PRIME MINISTER TAYYIP ERDOGAN SAYING:

"We don't believe, we don't trust him with the chemical weapons. Seven millions of people are displaced now and the Syrian regime will continue its massacres."

And as another Russian warship enters the Mediterranean ..... Russian President Vladimir Putin appealed to U.S. public opinion with a New York Times op-ed, saying a military strike would - quote -- "unleash a new wave of terrorism."

But a Western-backed Syrian rebel council released video rejecting outright the Russian proposal, calling on Assad to be tried instead in the International Criminal Court.

The rejection comes as rebels release video of what they say is the aftermath of a government bombing on a rebel-held hospital, killing 11 people including children.
