Damascus: A Syrian Army colonel said on Saturday that he has defected with "hundreds" of soldiers and warned the regime against launching a crackdown on the eastern oil hub of Deir az-Zour.
The man, identifying himself as Colonel Riad al-Asaad, said that he was speaking from inside Syria "near the Turkish border”.
"I am the commander of the Syrian Free Army," he said.
"We are hundreds," he added of the number of troops under his command.
The claim could not be independently verified.
But the caller warned the Syrian regime against carrying out any security operations in Deir az-Zour, where activists said a massive military convoy, including tanks, deployed on Saturday.
"I warn the Syrian authorities that I will send my troops to fight with the [regular] Army if they do not stop the operations in Deir az-Zour," Al-Asaad said.
Earlier, the head of the Syrian Observatory for Human Rights based in Britain said soldiers shot dead three stone-throwers as a convoy of 60 military vehicles made its way towards Deir az-Zour.
Rami Abdel Rahman, quoting witness in the city, said the troops deployed in Deir az-Zour, with some of them taking positions near the offices of the governor.
Deir az-Zour is at the forefront of more than four months of anti-regime protests and scene of a deadly crackdown by the Syrian authorities against dissent.
