ISIS recently released what’s been called its “most barbaric video yet,” purportedly showing Jordanian Lt. pilot Muath al-Kaseasbeh being burned alive.
The video shows al-Kaseasbeh doused and surrounded by lines drawn in the sand with flammable liquid, which are then ignited, causing the captive to burst into flames.
Jordan wasted no time in responding to the ISIS attack. 
According to the BBC:
Jordan has executed two convicts, including a female jihadist, following the killing of one of its air force pilots by Islamic State (IS) militants.
The woman, failed suicide bomber Sajida al-Rishawi, and al-Qaeda operative Ziyad Karboli - both Iraqi nationals - were hanged at dawn, officials said.
The executions came hours after IS posted a video appearing to show pilot Moaz al-Kasasbeh being burned alive.
