Italy on Sunday lifted a travel warning for Egyptian beach resorts imposed last year but continued to advise tourists to stay away from other parts of the country, saying there was still "instability and turbulence".

The foreign ministry had issued the warning in August 2013 following Islamist president Mohammed Morsi's ouster by the military and a crackdown on protests.

President Michel Suleiman on Sunday announced that he has asked security forces to protect Lebanese towns near the border with Syria “from any attack.”

“Suleiman has asked military and security officials to take all the necessary measures to protect Lebanese villages and towns near the border with Syria,” said a message published on the president's Twitter account.

The United States Saturday called on Egypt to fully implement the rights guaranteed under its newly approved constitution.

Egyptian voters approved the constitution by more than 98 percent in a referendum result that the government hailed as a popular endorsement of the army's overthrow of Islamist President Mohammed Morsi.

Egyptian voters have approved a new constitution by 98.1 percent, the elections chief said Saturday, in what the government declared a popular endorsement of the army's overthrow of Islamist president Mohammed Morsi.

The result of the Tuesday-Wednesday vote had never been in doubt, as Morsi's Muslim Brotherhood and other Islamists boycotted it, but the authorities wanted a large turnout in the first democratic test since the ouster in July.

Officials are to announce Saturday the results of a constitutional referendum likely to set the stage for a presidential bid by the army chief who toppled Egypt's first freely elected head of state.

Initial tallies suggest this week's two-day referendum passed with an overwhelming majority, in what the military-installed government said was a strong stamp of approval for the overthrow of Islamist president Mohammed Morsi.

At least three people were killed in clashes in Egypt Friday as police dispersed protesters loyal to ousted Islamist president Mohammed Morsi, security officials and the health ministry said.

Police clamped down on protests in several cities, firing tear gas at Islamists, who aimed fire works at the riot police in one incident, police officials said.

Islamist backers of ousted Egyptian president Mohammed Morsi called for protests Friday ahead of the release of results from a constitutional referendum they mocked as a return to the bad old days of authoritarianism.

The military-installed interim authorities trumpeted the two-day poll as a chance for voters to endorse the army's overthrow of Egypt's first freely elected president last July after mass protests on the streets.

Egyptian prosecutors accused three detained Al-Jazeera journalists, including an Australian and a Canadian, on Thursday of broadcasting false news in the service of the now terror-blacklisted Muslim Brotherhood.

The three journalists were arrested on December 29 in a Cairo hotel. They include Peter Greste, an acclaimed Australian reporter who formerly worked for the BBC, and Canadian-Egyptian Mohamed Adel Fahmy.

Egypt's presidency hailed on Thursday the "high turnout" in a constitutional referendum, billed by the military-installed government as an endorsement of the overthrow of Islamist president Mohammed Morsi in July.

The president's spokesman "remarked, on the high turnout in the referendum, that it was a beautiful day for Egypt and democracy," a statement said.

Egypt awaited Thursday results of a referendum on a new constitution that could launch a presidential bid by the army chief, with initial tallies indicating overwhelming support for the charter.

Given a boycott by the Islamist opposition, the result has never been in doubt, but the military-installed government is hoping for a large turnout to bolster its democratic credentials after the overthrow of President Mohammed Morsi.
