Latest developments in the unrest sweeping the Arab world from North Africa to the Persian Gulf:
Soldiers and riot police in Bahrain overran a protesters' camp, imposed a 12-hour curfew and choked off movement across the nation. Witnesses described helicopters firing on homes and attacking doctors treating the wounded, while the government called the demonstrators "outlaws" for demanding an end to the Sunni monarchy.
The island nation went into lockdown, its government propped up by troops from Sunni Gulf neighbors fearful for their own rule and the spread of Shiite Iran's influence.
Libyan rebels battled to hold the strategic eastern city of Ajdabiya against an offensive by forces loyal to Moammar Gadhafi, voicing anger and frustration at the West for not coming to their aid. Government troops heavily shelled Misrata, the last main rebel bastion near the capital.
Supporters in the U.N. Security Council were trying to push through a resolution to impose a no-fly zone along with other measures aimed at preventing Gadhafi from bombing his people, but Russia and Germany have expressed doubts.
Government supporters armed with sticks, knives and guns attacked thousands of protesters, wounding hundreds in an increasingly violent crackdown on demonstrations calling for Yemen's longtime president to step down.
After nearly a month of protests, about 50 demonstrators have been killed in the country, said Amal al-Bashi, of the Yemen Center for Human Rights. Protesters demand that President Ali Abdullah Saleh leave office after 32 years in power.
U.S. Secretary of State Hillary Rodham Clinton went to Tahrir Square, symbolic heart of Egypt's popular uprising, and praised the demonstrators who brought down longtime leader Hosni Mubarak.
Clinton said she hoped people everywhere would look back on the revolt and regard it as "one of the most important historic turning points" in the Middle East.
