Amman, Jordan ? The four-person team of Iraqis who committed last week’s coordinated hotel bombings crossed the border days earlier with ready-made suicide belts, a Jordanian official said Saturday.

A senior Jordanian security officer, speaking on condition of anonymity, confirmed that a woman was among the bombers in Wednesday’s attacks, which left 57 people dead in three Amman hotels. He said the attacks were ordered by Abu Musab al-Zarqawi, the Jordanian-born militant who leads al-Qaida in Iraq.

The new information matches that of an Internet statement posted Friday in al-Zarqawi’s name, which described the bombers as four Iraqis, including a husband and wife.

The identities of the bombers are expected to be announced as early as today.

The official said the remains of a woman were found at the Radisson SAS hotel, where the bombing ripped through a crowded wedding. The woman was not apparently one of the wedding guests.

A Jordanian woman lights candles Saturday to mourn those killed and injured in the hotel bombings in front of the Radisson hotel where a suicide bomber struck Wednesday in Amman, Jordan. King Abdullah II is calling for a global effort to fight terrorism after Jordan acknowledges for the first time that al-Qaida in Iraq used four foreign suicide bombers to launch the hotel attacks that killed 57 others.

The official theorized that the husband and wife came as a couple so as to more easily blend into the wedding crowd. It was unclear whether she also carried a bomb.

The team crossed into Jordan from Iraq on Nov. 7, and all stayed in the same Amman safe house. The person who rented the house shortly before their arrival remains at large, the official said.

They arrived carrying completed explosive belts apparently made from Iraqi military materials. The official described the belts as sophisticated devices capable of being transported on long overland journeys without danger of accidental detonation.

The belts contained RDX, a military explosive that the official said is not found in Jordan. The detonators were salvaged from Yugoslav-made hand grenades such as those previously used by the Iraqi army under Saddam Hussein, the official said.
