Libya: Egypt's military said it bombed ISIS targets in Libya at dawn on Monday, following a video showing the execution of a group of Egyptian Copts by the militant group.

‘Your armed forces on Monday carried out focused air strikes in Libya against Daesh camps, places of gathering and training, and weapons depots,’ the military said in a statement, using the Arabic acronym for ISIS.

On Sunday, ISIS released a video purportedly showing the beheading of 21 Egyptians captured in Libya. President Abdel Fattah al-Sisi called an urgent meeting of Egypt’s top national security body after the video was released.

Sisi also gave a televised address, saying that Egypt and the world are facing ‘ferocious threats’ hailing from radical militants, who are ‘devoid of any humane sense.’

He said his country reserved the right to ‘punish these murderers’ as he called a meeting of security chiefs and declared seven days of mourning after the video was distributed by militants on social media.

Egypt’s Coptic Orthodox church said it was ‘confident’ that those who purportedly beheaded a group of Egyptian Copts in Libya will be punished.

In a separate development, the United States condemned as ‘despicable’ the beheading of the 21 men.
