Hundreds of Syrian soldiers stormed the Damascus suburb of Saqba and rounded up residents, witnesses said May 5. Sweeps were also reported from the Homs suburb of Rastan, where security forces shot dead at least 17 demonstrators six days earlier.

Among the detained is AlJazeera reporter Dorothy Parvaz.

The lack of reaction to the apparent killing of Osama bin Laden is in some ways more telling than the reaction. For starters, thank goodness, the feds have not issued a terror alert. Politico notes on May 4:

When President Barack Obama announced that Osama bin Laden had been killed, there was no color-coded chart in the corner of the TV screen to alert Americans that the government had raised the threat level from yellow to orange.

An explosion ripped through a military vehicle in the southern Yemeni town of Zinjibar May 4, killing five soldiers, while four civilians died in the ensuing firefight. The blast hit the vehicle close to a busy market selling khat, the mildly stimulating leaf (considered haram by al-Qaeda). The blast came hours after an unnamed leader of al-Qaeda in the Arabian Peninsula (AQAP) vowed revenge for the killing of Osama bin Laden. "We will take revenge for the death of our Sheikh Osama bin Laden and we will prove this to the enemies of God," the spokesman told AFP, contacted by telephone from Yemen's southern province of Abyand. "The martyrdom of Sheikh Osama does not mean that jihad will end." (AP, AFP, May 4)

At least nine were killed and more than 100 wounded as troops opened fire on anti-regime protesters in Sanaa, capital of Yemen, on April 27.

Hundreds of young activists protested outside the Saudi embassy to oppose the plan brokered by the Gulf Cooperation Council that calls for Saleh's staggered exit from power. "Youth of the revolt reject the Gulf initiative," said a banner carried by the protesters outside the embassy. (Middle East Online, April 28)
