Muslim clerics widely condemned the burning to death of a Jordanian pilot by Islamic State, saying such a form of killing was considered despicable by Islam, no matter the context.
Islamic State militants released a video on Tuesday appearing to show captured pilot Mouath al-Kasaesbeh being burnt alive in a cage. Jordan, which has participated in a US-led military campaign to bomb Islamic State positions, responded overnight by executing two al-Qaida convicts on death row.
Egypt's top Muslim authority, the 1,000 year old Al-Azhar university revered by Sunni Muslims around the world, issued a statement expressing "deep anger over the lowly terrorist act" by what it called a "Satanic, terrorist" group.
The Grand Sheik of Al-Azhar, Ahmed al-Tayeb, said the killers themselves deserved to be "killed, crucified or to have their limbs amputated."
