LIBYA The Libyan rebels' military commander is killed by his comrades while in custody after he was arrested by the opposition's leadership on suspicion of treason, witnesses say, in a sign of disarray that posed a major setback for the movement battling Muammar Gadhafi. The slaying of Abdel-Fattah Younis raised fear and uncertainty in Benghazi, the de facto rebel capital. SYRIA Tens of thousands of protesters calling for the ouster of President Bashar Assad's regime take to the streets throughout Syria, urging fellow citizens who have remained on the sidelines to join them and warning those who are hesitant that they are indirectly helping security forces kill more protesters. Syrian troops trying to sweep them from the streets fire live ammunition and tear gas, killing at least four demonstrators, activists say. EGYPT Tens of thousands of ultraconservative Muslims in long beards, robes and prayer caps throng Cairo's central Tahrir Square in a massive show of force, calling for the implementation of strict Islamic laws and sparring with liberal activists over their visions for a post-revolution Egypt. It was the first rally with religious overtones in Egypt, and one of the largest, since the uprising that forced President Hosni Mubarak to step down in mid-February. BAHRAIN Thousands of demonstrators take to the streets outside Bahrain's capital to call for greater democratic freedoms despite government plans to introduce some political reforms. The march comes a day after Bahrain's king accepted a list of proposed reforms that include strengthening the power of parliament's lower house, the country's only elected body. JORDAN Members of Jordan's powerful Islamist opposition have taken an oath to continue peaceful protests until their demands for political reform in the kingdom are met. Around 3,000 Muslim Brotherhood activists took the oath, raising their right hands during a protest in Amman on Friday.
