A video release by the extremist group ISIS purportedly shows the execution of the Jordanian pilot held by the group. The pilot, Lt. Moaz al-Kasasbeh, was burned alive inside a cage. Both the U.S. and the Jordan have condemned ISIS's actions.

The New York Times reports the latest video from ISIS depicts the execution of the 26-year-old Jordanian fighter pilot whom ISIS captured in December after he ejected from his F-16 fighter jet. The highly produced 22-minute long video shows Lt. al-Kasasbeh wearing the same orange jumpsuit worn by previous ISIS captives. He then appears in a black cage, apparently doused in a flammable liquid, then a hooded ISIS fighter ignites a trail of fuel and the flames engulf the prisoner.

The Kingdom of Jordan had previously said it "will do everything it can to save the life and secure the release of its pilot," according to the AFP. Government spokesperson Mohammed al-Momeni added: "All state organizations have been mobilized to secure the proof of life that we require so that he can be freed and returned to his home."

However, following the beheading of Japanese journalist Kenji Goto, the chances Lt. al-Kasasbeh remained alive were slim. According to Reuters, the incident has sparked protests against King Abdullah II over the government's handling of the crisis. The government had said it would exchange convicted terrorist Sajida al-Rishawi for the pilot.

The government has also informed the pilot's family about his passing. State television also reported that Lt. al-Kasasbeh was executed a month ago, casting doubts over ISIS's sincerity concerning the negotiations.

"While the military forces mourn the martyr, they emphasize his blood will not be shed in vain. Our punishment and revenge will be as huge as the loss of the Jordanians," Jordanian armed forces spokesperson Mamdouh al-Ameri said in a statement, according to the Associated Press. He referred to Lt. al-Kasasbeh as a "hero pilot."

U.S. President Barack Obama also condemned the killing and said the video was being authenticated, reports AFP.

"Should in fact this video be authentic, it's just one more indication of the viciousness (and) barbarity of this organization," he said, adding that his government would continue to work with the coalition until ISIS is "ultimately defeated.

Secretary of State John Kerry, who had been meeting with King Abdullah just hours earlier, released a statement as well, in which he called Lt. al-Kasasbeh "brave, compassionate, and principled."

"The United States extends its deepest condolences to Lieutenant al-Kasasbeh's family, King Abdullah II, the Jordanian Armed Forces, and the people of Jordan. Jordanians have demonstrated extraordinary compassion by opening their borders to the flow of refugees precipitated by the violence in Syria and Iraq," he said, adding that the Jordanian pilot's bravery, as well as that of all coalition pilots, helps erode ISIS's control and halt its advance.

"We will never allow the scourge of ISIL to spread to other countries, or the death of Lieutenant al-Kasasbeh and thousands of innocent victims to be forgotten," Sec. Kerry said. "Our support for the Arab coalition united against this terrorist organization will not rest until ISIL can no longer threaten the region and their lies and deceptions are clear to all."
