Russian President Vladimir Putin told visiting Syria peace mediator Kofi Annan on Tuesday that he would “do everything” to support the UN-Arab League envoy’s plan to end the conflict.

“From the very start, from the first steps, we supported and continue to support your efforts aimed at restoring civil peace,” Putin told Annan at the start of their Kremlin meeting.

“We will do everything that depends on us to support your efforts,” the Russian leader said.

The international envoy replied that “the Syrian crisis is at a critical time” before the meeting was closed to the press.

British Foreign Secretary William Hague said on Tuesday the crisis in Syria is too unpredictable to rule out “any option,” insisting that a Chapter VII resolution of the US Security Council is needed. “The situation (in Syria) is so grave and so unpredictable that I do not think any option should be ruled out in the future,” Hague said in Amman at a joint news conference with his Jordanian counterpart, Nasser Judeh.

“Clearly, we have failed so far. The process that (peace envoy) Kofi Annan has launched has failed so far to bring about a peaceful political process and so now we need the Security Council to greatly strengthen the pressure for that to happen.”

Hague urged Russia and China to “take greater note of the scale of the bloodshed and the need to bring it to an end and the desperate situation of the sort of people that we met at the Syrian border today.” Earlier Tuesday, Hague and Judeh met with Syrian refugees in the border town of Ramtha, where the British minister slammed the “barbarity and criminality of the Assad regime.”

“What we have seen today should leave us in no doubt at all that a Chapter VII resolution is required,” Hague told the press conference. Chapter VII of the UN charter allows for punitive measures against regimes considered a threat to world peace, including economic sanctions and military intervention.

Hague added that this is “to mandate the implementation of Annan’s peace plan and a transitional government in Syria with a peaceful political process and to bring about the imposition of globally agreed sanctions on those who obstruct the implementation of that plan.”

Hague also toured Ramtha’s Bashabsheh housing complex, a military-guarded compound that houses around 1,000 Syrian refugees.

“It is horrible to hear the accounts of what is happening (in Syria) from people here, many of them coming from close by over the borders,” said Hague, the most senior British official to visit the refugees in Jordan.

The news reports that are coming out of Syria, “assure the barbarity and criminality of the Assad regime.” “The horrors of the crimes committed by Assad are clearly on display when you talk to people just over the borders from Syria,” he told reporters.

Turkey is building a new refugee camp for Syrian refugees to accommodate 10,000 people, officials said on Tuesday, as hundreds more people fled the escalating violence.

The state-run Anadolu agency reported that at least 864 people had crossed the border into Turkey since Monday, including a general and four colonels.

A new camp is being set up near the town of Karkamis, in Gaziantep province on the border with Syria, Turkey’s crisis management centre said. The camp will have a capacity to accommodate 10,000 people.
