Jordan has executed two prisoners after Islamic State murdered one of their pilots, a government spokesman has said.
One of those executed was Iraqi would-be suicide bomber Sajida al Rishawi, who was on death row for her role in a hotel attack that killed 60 people.
The other was Ziad al Karbouli, who had been an aide to the late former leader of Al Qaeda in Iraq, Abu Musab al-Zarqawi, and who was sentenced to death in 2008 for plotting terror attacks on Jordanians in Iraq.
The two jihadists were hanged in Swaqa prison, a large facility 70km (45 miles) south of the capital, Amman, just before dawn, a security source told Reuters.
"They were both calm and showed no emotions and just prayed," the source added.
Jordan had promised a swift and lethal response after IS released a video showing captured pilot Mu'ath Al Kassasbeh being burned alive in a cage.
Michael Stephens is Middle East Research Fellow at the Royal United Services Institute in Qatar, and he spoke to Newstalk Breakfast about Islamic State's actions and Jordan's response:
Colin Freeman, chief foreign correspondent with the Sunday Telegraph, also spoke to the show. You can listen to the full interview below:
IS had demanded the release of Rishawi in exchange for Mr Al Kassasbeh and Japanese journalist Kenji Goto, who the militant group killed in a video posted online three days ago.
Jordan had agreed to the swap, but called off the deal after saying it had received no proof that the pilot was still alive.
Some Arab commentators had suggested jihadist Al Karbouli could also form part of a prisoner swap.
The killing of the pilot outraged Jordanians and drew worldwide condemnation, including from President Barack Obama and the UN Security Council.
President Obama called it 'one more indication of the viciousness and barbarity' of Islamic State:
The pilot's father, Safi, has said he "considers Mu'ath a martyr to God", and called on the Jordanian government "to take revenge for Mu'ath's blood".
He added: "The blood of Mu'ath is this country's blood. The country has to take its revenge, and I call for no one to remain alive from Islamic State, I call for revenge by executing prisoners, and I call to erase the Daesh organisation
Mr Al Kassasbeh was captured by the militants in December when his F-16 crashed near Raqqa, Syria, the de facto capital of the Islamic State group's self-styled caliphate.
The 26-year-old's murder appeared to be aimed at pressuring the government of Jordan - a close US ally - to leave the coalition that has carried out months of airstrikes on IS positions in Syria and Iraq.
But observers say the extremists' brutality against a fellow Muslim could backfire and galvanise other Sunni Muslims in the region against them.
King Abdullah II, Jordan's leader, has portrayed the campaign against the extremists as a battle over values.
In a speech on Jordanian state television, he urged his countrymen to unite.
"It's the duty of all of us to stand united and show the real values of Jordanians in the face of these hardships," the monarch said from Washington.
