Saudi Arabia's interior ministry said on Saturday that protests were illegal, amid various calls for demonstrations demanding change in the ultra-conservative kingdom, state media said.

"Regulations in the kingdom forbid categorically all sorts of demonstrations, marches and sit-ins... as they contradict Islamic Sharia law and the values and traditions of Saudi society," said a ministry statement carried by SPA state news agency.

Two men were killed during clashes in Egypt between Muslims and Christians, and a church was set on fire in the village of Sol, south of Cairo, a security official said on Saturday.

Two Iranian warships, which entered the Mediterranean last month sparking an outcry from Israel, have passed through the Suez Canal back into the Red Sea, naval commander Rear Admiral Habibollah Sayari said on Saturday.

Up to 10 people were killed and more than 20 wounded in clashes between Libyan rebels and loyalists of MoammAr Gadhafi in the oil town of Ras Lanuf, doctors said Saturday.

Egypt's former interior minister Habib al-Adly pleaded not guilty to corruption charges on Saturday, in the first trial of a member of ousted president Hosni Mubarak's regime.

At least 17 people were killed Friday when a huge explosion ripped through a military weapons depot outside Benghazi, the main city held by Libyan rebels fighting Moammar Gadhafi.

Dr. Habib al-Obeidi in Benghazi's al-Jalaa hospital said the blast also hit a residential area. Witnesses on the scene, about 32 kilometers from downtown, said ambulances were rushing to the area and secondary explosions caused two fire trucks to blow up.

Egypt's new Prime Minister Essam Sharaf vowed on Friday to respond to demands for democratic change as he addressed thousands of protesters in Cairo's Tahrir Square a day after his appointment.

Libyan police fired tear gas at protestors demonstrating against Moammar Gadhafi's regime in Tripoli Friday as rebel fighters in eastern Libya tried to push the front line nearer to the capital.

Forces loyal to Libyan leader Moammar Gadhafi were battling rebels on Friday for control of the town of Zawiyah, near Tripoli, in heavy fighting that has left "many dead," witnesses said.

Interpol has issued a global alert against Libyan leader Moammar Gadhafi and 15 others, including members of his family and close associates, the global police organization said on Friday.
