Egyptian President Mohammed Morsi has said Egypt has decided to cut all ties with Syria and will withdraw the country's envoy from Damascus.
Addressing a gathering of Sunni Muslim clerics in Cairo, Morsi said: "We decided today to entirely break off relations with Syria and with the current Syrian regime."
He also warned Assad's allies in the Iranian-backed Lebanese Shi'ite militia to pull back from fighting in Syria.
"We stand against Hezbollah in its aggression against the Syrian people," Morsi said.
"Hezbollah must leave Syria - these are serious words. There is no space or place for Hezbollah in Syria."
