Watch: Egyptian airstrikes against IS in Libya

An amateur video emerged on Monday showing an Egyptian airstrike against Islamic State group targets in the Libyan city of Darna. The video shows Darna's skyline and smoke rising behind buildings from the airstrike. Egypt said that its warplanes had struck Islamic State targets in Libya in swift retribution for the extremists' beheading of a group of Egyptian Christian hostages on a beach, shown in a grisly online video released hours earlier. At the same time, Egypt called for international intervention in Libya against the Islamic State group.
