Jordan has executed female suicide bomber Sajida al-Rishawi following the release of an Islamic State (Isis) video showing captured Jordanian pilot Moaz al-Kasasbeh being burnt alive.
Jordan's state-run news agency said a senior al-Qaeda commander, who was convicted of plotting terror attacks in Jordan, has also been hanged.
Shortly after IS released a video of the execution of the Jordanian pilot, who had been captured by the militants after his F-16 crashed in Syria, Jordan said the death row convicts would be executed.
Al-Rishawi, 44, was imprisoned in Jordan after attempting to detonate an explosives belt as part of the devastating 2005 hotel bombings in the capital city of Amman.
Jordan vowed to give an "earth-shattering" response to the IS militants after it emerged that they had executed the pilot al-Kasasbeh.
A statement from the Jordanian army said: "The military forces announce that the hero pilot, Muath al-Kaseasbeh, has fallen as a martyr, and ask God to accept him with the martyrs.
"While the military forces mourn the martyr, they emphasise his blood will not be shed in vain. Our punishment and revenge will be as huge as the loss of the Jordanians."
Jordan's King Abdullah has also decided to cut short his visit to the US following the incident and has headed back to his country.
