(CNN)Egypt's military carried out a series of airstrikes against ISIS militants in Libya on Monday in retaliation for the slaughter of 21 Egyptian Christians by the jihadist group. The bombing raids pulled Egypt deeper into the widening international fight against ISIS and highlighted the extremists' growing presence in North Africa. The warplanes hit 10 targets used for training and storage in ISIS' Libyan stronghold of Derna, Egyptian Foreign Minister Sameh Shoukry told CNN. "Avenging Egyptian blood and punishing criminals and murderers is our right and duty," the Egyptian military said in a statement that was broadcast on state television. There were conflicting claims about what the bombs had struck.
