Muslim Brotherhood supreme guide Mohammed Badie told a crowd of supporters of Egypt's ousted president Friday that protesters will remain mobilized until Mohammed Morsi's return after he was deposed by the military.

"Millions will remain in the squares until we carry our elected president, Mohammed Morsi, on our shoulders," Badie told the cheering crowd.

Turkey's prime minister on Friday condemned the military intervention that toppled Egypt's Islamist president Mohamed Morsi as an enemy of democracy, and chastised the West for failing to brand the ouster a coup.

Referring to his country's history of coups, Recep Tayyip Erdogan warned that such military uprisings come at a heavy price and must not be tolerated.

Ismail Haniya, head of the Hamas government in Gaza, appealed in a Friday sermon to have faith in the Arab Spring despite the ouster of Egypt's Islamist president Mohamed Morsi by the army.

"Do not fear for the Palestinian cause or for the resistance (against Israel) or for Gaza. Egypt is behind us, as are the Arab and Islamic countries," Haniya said.

Running clashes erupted on Friday evening between supporters and opponents of Egypt's ousted Islamist president Mohamed Morsi near Cairo's Tahrir Square.

The sound of gunfire could be heard as the two sides hurled rocks at each other on the October 6 bridge leading into Tahrir. Below the bridge, ambulances were ferrying the injured out of the area.

The African Union suspended Egypt from the continental body Friday after the ouster of president Mohammed Morsi, in line with its strict rules against unconstitutional changes of government.

The United Nations food agencies on Friday appealed for more funds to help an estimated four million Syrians unable to produce or buy enough to eat as a new report detailed a farming sector severely hit by the conflict.

The Food and Agriculture Organization said it had only received 10 percent of the $41.7 million (32.4 million euros) it needed to assist 768,000 farmers, while the World Food Program said its operations were "only 48 percent resourced".

Debra Tice wakes up each morning hoping her life will have changed and the 11 months since her son Austin disappeared in Syria will turn out to have been a bad dream.

But since she and her husband Marc learnt that their 31-year-old first-born had gone missing while reporting in the war-torn country, not a single morning has given her that relief.

U.N. human rights chief Navi Pillay Friday expressed alarm about reported mass arrests of key members of Egypt's Muslim Brotherhood after the military ousted president Mohammed Morsi, and urged all sides to respect fundamental freedoms.

"There should be no more violence, no arbitrary detention, no illegal acts of retribution," Pillay said in a statement.

Explosions rocked several army ammunition depots in the western Syrian province of Latakia on Friday, possibly after they were targeted with rockets, the Syrian Observatory for Human Rights said.

Observatory director Rami Abdel Rahman said there were reports of deaths and injuries in the blasts but he had no further details.

Attacks killed five people in town squares in Iraq on Friday, including four who died when a suicide bomber set off his vehicle rigged with explosives just before midday prayers.

The latest violence, which left dozens wounded, comes as Iraq struggles with a surge in violence coinciding with a long-running government deadlock and months of protests among the Sunni Arab minority.
