Egypt launches second wave of airstrikes on ISIS in Libya

Egyptian warplanes staged a second wave of airstrikes against ISIS targets in Libya on Monday in retaliation for the slaughter of 21 Egyptian Christians by ISIS militants, Egypt’s state-run Ahram Online reported, citing security officials.

The airstrikes came after an earlier wave that struck ISIS camps, training areas and weapons depots, the military said.

“Avenging Egyptian blood and punishing criminals and murderers is our right and duty,” the Egyptian military said in the statement, which was broadcast on state television.

Video appears to show beheadings of Egyptian Christians

The bombing raids came after ISIS released a gruesome video Sunday that appeared to show ISIS militants beheading men they said were Christians on a beach.

The slickly produced video shows the apparent mass killing, with jihadists in black standing behind each of the victims, who are all dressed in orange jumpsuits with their hands cuffed behind them.

Twenty-one Egyptian Christians were kidnapped in the Libyan coastal city of Sirte in two incidents in December and January. They were reportedly from impoverished villages and went to Libya looking for work.

Now, U.S. intelligence and government officials say Mueller possibly was paired with a male ISIS fighter during her captivity.

The officials, speaking on condition of anonymity, cited unspecified intelligence gleaned about the case. A U.S. intelligence official said it was unclear whether Mueller was sold or forced into the pairing.

Intelligence suggests Mueller may have been given to an ISIS fighter as a sort of bride, one U.S. government official said.
