The UN has condemned Syria for its use of heavy weaponry in the town of Houla, where at least 108 people were killed on Friday.

World public opinion has "dramatically shifted" against the Syrian regime following the attack, LSE Professor Fawaz Gerges told the Today programme.

But, he said, the international community does not have the "desire or will" to intervene in the country.

"The rot has set in," he said. "It feels and smells like a civil war."
