Morsi told his supporters in Cairo on Saturday that he decided to “definitively break off relations with the current regime in Syria, ” a news agency reported.
He also called for foreign support for insurgents in the country.
He added that his government would also be recalling the Egyptian charge d ' affaires from Damascus.
In addition, Morsi called on Western states to enforce a no - fly zone over Syria.
The United States has recently announced that it will impose a no - fly zone over Syria and the Pentagon is drawing up plans for the action.
Elsewhere in his remarks, Morsi urged the Lebanese resistance movement Hezbollah to withdraw from Syria. " Hezbollah must leave Syria - - these are serious words. There is no space or place for Hezbollah in Syria. "
In late May, Hezbollah Secretary General Seyyed Hassan Nasrallah said that members of the resistance movement were battling the militants alongside Syrian government forces in the strategic border town of al - Qusayr - - an important center and supply route for the foreign - sponsored militants.
On June 5, the Syrian army recaptured al - Qusayr after three weeks of fighting.
The Syria crisis began in March 2011, and many people, including large numbers of government forces, have been killed.
