Armed regime loyalists opened fire on protesters in a square they have been occupying at Yemen's Sanaa University March 18, killing at least 32 and leaving some 200 wounded. Parliamentary opposition spokesman Mohammed al-Sabri accused the regime of a "massacre" and said "these killings will not help keep Ali Abdullah Saleh in power." Thousands of people have camped out in the square since Feb. 21, demanding the departure of Saleh, a US ally who has held power since 1978. Police also fired warning shots as thousands marched in the southern port of Aden. Opposition leaders say over 70 have been killed since the anti-regime protests began this year.

Some 200 Syrians defied a state emergency in place since 1963 to gather in Damascus to demand a political opening March 15. "God, Syria, liberty" and "Syrians, where are you?" chanted young men and women, urging their compatriots to join the "peaceful march" which unfolded in a central souk of Old City Damascus. The protesters marched through landmark souks al-Hamidiyeh and Hariqa, drawing dozens of other Syrians with them. But security forces broke up the group and arrested two.

Hundreds of riot police backed up by tanks, bulldozers and helicopters killed at least two and wounded dozens more March 16 as they cleared a protest camp in Bahrain's Pearl Square.

Saudi-led forces from the Gulf countries' joint Peninsula Shield Force crossed the international causeway into Bahrain March 14 to help restore order after protesters shut down Manama's financial center the previous day, sparking hours of street clashes. The incursion by the 1,000-strong force came in response to a request form the Gulf Cooperation Council (GCC), which groups Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates. Responding to a reporter's question about the incursion, White House spokesman Jay Carney told a news briefing: "We've seen the reports that you're talking about. This is not an invasion of a country. We urge the government of Bahrain, as we have repeatedly, as well as other GCC countries, to exercise restraint." (Middle East Online, Reuters, March 14)

Two protesters died in Yemen on March 13, a day after being shot by police in the southern city of Aden, raising the death toll to seven in demonstrations against President Ali Abdullah Saleh. There were also disturbing reports from the capital, Sanaa, of protesters passing out and going into convulsions after inhaling gas fired by police. "This isn't tear gas," said Iraqi doctor Hussein al-Joshaai, a nerve specialist who was at the scene. "This is poison gas that disables the nervous and respiratory systems." Another doctor, Abdulwahab al-Inssi, said: "Those wounded today couldn't have been hit by tear gas grenades. They are suffering spasms." The interior ministry denied the allegations as "baseless slander." (Middle East Online, March 13)

Bahrain's crown prince Salman bin Hamad al-Khalifa is expected to formally invite Saudi forces into his country, as part of a request now being considered by the six-member Gulf Co-operation Council. Hundreds were injured after police fired tear gas and charged protesters who had occupied Manama’s financial center on March 13.

Four were killed in fighting between anti-government protesters and security forces in Yemen March 12, even as President Ali Abdullah Saleh promised the White House that he would not use violence against the demonstrators. At least three people were killed in the capital, where some 100,000 staged a sit-in at Sanaa University to demand Saleh's ouster. As police used tear gas to break up the sit-in, pro-government snipers opened fire from rooftops. The fourth casualty, a 14-year-old boy, was killed in a protest the southern port city of Mukalla. In a bid to counter what he called "sedition," Saleh went on TV to pledge a referendum on a new constitution later this year, which would devolve further powers to parliament. But the move was dismissed by the opposition. "The president's initiative is too late and constitutes the last breath of the political regime which protesters demand and end to," parliamentary opposition spokesman Mohammad al-Sabri said.
