Developments on unrest in the Middle East and North Africa:

SUNDAY

[OMAN, 9:00 a.m. ET, 6:10 a.m. local] At least two protesters were killed and about 10 injured during clashes between protesters and police in the Omani industrial town of Sohar, according to reports from state media and Oman TV editor Asma Rshid. "The police shot them because they burned shops and cars in Sohar," Rshid said. Another source said police fired rubber bullets.

[LIBYA, 9 am ET, 4:15 p.m. local] Protests are picking up in Libya's western city of Zawiya with former security forces who said they have switched sides and joined the opposition.

The United Nations Security Council unanimously approved a draft resolution to impose sanctions against Libya amid escalating attacks on anti-government protesters in the north African country.

The resolution draft includes an arms embargo, asset freeze and a travel ban. It also refers Libya to the International Criminal Court.

SATURDAY

[TUNISIA, 9:12 p.m. ET, 3:12 a.m. local] Protests in Tunisia turned violent and deadly Saturday, just over six weeks after a popular uprising forced the president out of office, and lit a spark of desire for democratic reform in parts of Africa and the Middle East.

Three people were killed Saturday and nine others injured during mayhem in the capital, Tunis, according to a Interior Ministry statement cited by the state-run news agency, Tunis Afrique Presse (TAP).

More than 100 people were arrested, the ministry said, in the area around Habib Bourguiba Avenue, in the city's center, accused of "acts of destruction and burning."

[LIBYA, 4:58 p.m. ET, 11:58 p.m. local] City councils in areas no longer loyal to Moammar Gadhafi have chosen former Justice Minister Mustafa Abdul Jalil to head an interim government which will represent all of Libya, according to Amal Bogagies, a member of the February 17 Uprising coalition, and a separate Libyan opposition source.

[LIBYA, 4:40 p.m. ET, 11:40 p.m. local] President Barack Obama, in a statement issued Saturday after reports that forces loyal to Libyan leader Moammar Gadhafi had fired on civilians, said "that when a leader's only means of staying in power is to use mass violence against his own people, he has lost the legitimacy to rule and needs to do what is right for his country by leaving now."

The White House statement was  issued after Obama spoke with German Chancellor Angela Merkel.

[BAHRAIN, 9:37 a.m. ET, 5:37 p.m. local] Exiled opposition leader Hassan Mushaima has arrived back in Manama, Bahrain. Mushaima, leader of the Haq Movement, had told followers earlier in the week that he had been detained in Beirut, Lebanon.
