The Insider: Daily Terrorism Report

Apr. 22 -- Today, a group called "Al Haramein Brigades" claimed responsibility for Wednesday's suicide car bombing in Riyadh, which killed four people and wounded 148. The statement, which was posted online, said the group has dedicated itself to fighting Saudi security forces, since al Qaeda's "mujaheddin" are preoccupied with their fight of "the crusaders," in reference to the U.S. The same group had twice claimed responsibility for assassination attempts on Saudi security officers in the past few months. Wednesday's bombing marked the third terror attack in the kingdom in less than a year, which have altogether killed over 50 people.

And in Jordan, a booby-trapped car, ready to be detonated, was found Tuesday in the Al Hashemi area, only hours before three terror suspects were killed by Jordanian security forces in the same area, Arab media reported today. This incident follows a week of terror round-ups, raids and weapons seizures in Jordan, where Jordanian authorities say only last week they thwarted a plan by members of Osama bin Laden's al Qaeda network to attack the U.S. embassy in Amman.

Saudi Bomb: Pro-Al Qaeda Claim

Editor's Note: There was a major public backlash against the last major al Qaeda bombing in Saudi Arabia on November 8, 2003. That attack on the Muhaya housing compound in Riyadh killed 17 people — all Arabs, Muslims and civilians. Al Qaeda tried to defend the operation, issuing statements that U.S. intelligence operatives were in the compound, a claim which was disregarded by many. In today's statement, al Qaeda makes clear that the target is the security police, a strategy which will likely find more support among the Saudi populace — a key condition for their campaign to overthrow the Sauds.
