The head of the exiled Syrian opposition said on Saturday that President Bashar al-Assad should be tried for "massacres" insisting that he should not be offered asylum in any future solution.

"The Yemeni example can't be applied in Syria," Syrian National Council chief Abdel Basset Sayda told reporters in Abu Dhabi, referring to the amnesty given to former Yemeni president Ali Abdullah Saleh following mass protests.

"There are massacres being committed. We believe Bashar (al) Assad should be tried. He is a criminal and should not be given a shelter," he added.

The SNC chief said the council would discuss a proposed transitional government with rebel groups on the ground, adding that its leader should be someone who had been committed to the uprising from the start.

"We are studying the idea (of transitional government) and we will contact all forces on the ground in Syria," he said.

The leader should be an "honest and patriotic person... committed to the objectives of the Syrian revolution since its beginning," he said.

He said that coordination would be in the first instance with groups on the ground, including the Free Syrian Army when he was asked about coordination with defector Brigadier General Manaf Tlas.

The former Syrian general is trying to plot the downfall of the Assad regime from a refugee camp in Turkey.
