Egyptian F-16s took off early Monday morning to bomb the ISIS training areas, weapons depots and camps in Libya said a military spokesperson from Egypt.
State television in Egypt broadcast a statement that said the military was avenging the Egyptian blood and punishing murderers and criminals is our duty and right.
The foreign ministry in Egypt said the airstrikes targeted locations of ISIS in Derna. It was not clear how many casualties or how much damage occurred from the bombings.
The bombings came after a gruesome video was released by ISIS that appeared to show Egyptian Christians being beheaded on a beach.
The video footage, which had many of the hallmarks from previous hostage executions, has intensified concerns internationally about the deepening reach of ISIS into countries beyond its strongholds in Iraq and Syria.
The video shows an apparent mass execution where jihadists dressed in black were standing behind each victim. All of the victims wore orange jumpsuits and had their hands handcuffed behind their backs.
Some hostages cried out Oh Jesus and Oh God, while being pushed down to their knees.
The video of five minutes in length released by al-Hayet Media the propaganda wing for ISIS includes a masked jihadi who is English speaking and says the sea that Sheikh Osama bin Laden’s body was hidden in, will be mixed with your blood.
Egypt, which has a border with Libya, was also threatened in the video along with Europe, which has shores just across the Mediterranean Sea.
Abdel Fattah el-Sisi the President of Egypt warned on Sunday that his country had the right to retaliate and with timing and methods, it sees fit for those criminals and murderers who do not have the slightest amount of humanity.
He declared one week of mourning in the nation dominated by Muslims for the murdered Christians.
The killings were condemned by the U.S. saying the barbarity has no bounds with ISIS.
