A look at the latest developments in political unrest across the Middle East on Tuesday:
A rebel military leader complains that NATO is not doing enough to batter Moammar Gadhafi's forces and break the siege of Misrata, the last rebel outpost near Tripoli. NATO says nearly a third of Gadhafi's heavy weapons have been destroyed in airstrikes, but Gadhafi's army drives rebels out of the vital oil port of Brega again. In a new tactic, Gadhafi forces move heavy weapons into the city in an attempt to protect them from NATO airstrikes.
An exchange of fire develops as leaders of President Ali Abdullah Saleh's tribe meet with a senior army officer who defected to the rebels. Three tribesmen are killed as Saleh hangs on to power despite loss of support among his people and even his own tribe. More than 120 people have been killed and 5,000 injured since Yemen's protests started in Feb. 11.
The government deports two Iraqi journalists working for the main Shiite opposition newspaper, the same one that was closed down for a day until its editor resigned. The strategic island kingdom has been rocked by demonstrations by majority Shiite Muslims protesting against a Sunni dynasty that has ruled for two centuries.
A Facebook campaign is launched to promote demonstrations the rest of the week in honor of more than 80 people killed during protests against the government of President Bashar Assad. In a town near Damascus, two police officers are shot dead, a rare occurrence in tightly ruled Syria. It is not clear if the killings are directly related to the protests.
Authorities say they have arrested a number of people gathering weapons, ammunition and firebombs for a demonstration planned for Friday in the northern industrial city of Sohar. No numbers of people arrested are given.
