Jordanian King Abdullah said on Sunday that a woman who failed to blow herself up in the triple suicide bombings in Amman on Wednesday has been arrested by the police.

"I have just learned that a fourth suicide bomber, a woman, who accompanied her husband to carry out the attack on the Radisson Hotel, has been in custody after failing to blow herself up," Abdullah told a group of reporters in the Jordanian capital Amman.

Three Iraqi men and one Iraqi woman, wife of one of the male bombers, carried out three coordinated suicide bomb attacks on the Radisson, Grand Hyatt and Days Inn hotels in Amman on Wednesday.

At least 57 people were killed and around 100 others wounded in the deadly attacks.

Al-Qaida terror group in Iraq, led by Jordanian militant Abu Musab al-Zarqawi, had claimed responsibility for the blasts and said in an Internet statement that an Iraqi couple along with two other men, also Iraqis, had carried out the bombings.

In the wake of the bloodshed, Abdullah vowed to hunt down the attackers and those behind the blasts. Scores of suspects have been rounded up by Jordanian police across the country and investigations are underway.
