Latest developments in Arab world's unrest

Here is a look at the latest developments in Mideast political unrest on Wednesday:



NATO ships patrol off Libya's coast as airstrikes, missiles and energized rebels force Moammar Gadhafi's tanks to roll back from two key western cities. In the east, civilians flee one strategic city while Libya's opposition takes haphazard steps to form a government. Confusion emerges about who will lead the international effort to enforce a no-fly zone, with the U.S. vowing to relinquish its lead role on Saturday.



Yemen's parliament enacts sweeping emergency laws after the country's embattled president asks for new powers of arrest, detention and censorship to quash a popular uprising demanding his ouster. The move escalates the showdown between Ali Abdullah Saleh and the protest movement that has unified military commanders, religious leaders and youth in demands for his immediate departure.



Syrian security forces shoot live ammunition and tear gas near a mosque then raid a neighborhood sheltering anti-government protesters, killing at least 15 people. Wednesday's crackdown in the southern city of Daraa marks the deadliest single day since anti-government protests inspired by uprisings across the Arab world reached this country last week. The latest deaths brings the number of people killed in Daraa since Friday to at least 22.



Protesters set up a tent camp in the capital of this Gulf kingdom, saying they'll stay until several ministers they accuse of corruption leave. Oman's ruler, Sultan Qaboos bin Said, has made sweeping Cabinet shake-ups since the start of strikes and sit-ins, staged by thousands of workers and pro-reform activists in the strategic nation since last month.
