Rishawi was arrested in 2005 and later sentenced to death in connection with a triple bomb attack on a hotel in Amman.
Rishawi`s husband and two other Iraqis are said to have blown themselves up in the Jordanian capital, killing at least 60 people.
In a televised confession after her arrest, Rishawi said that she too had tried but failed to detonate her explosives at a wedding reception.
