Airstrike said to kill 19 ISIS fighters in Sinai, including several commanders

Egyptian military sources said Thursday that 19 fighters including senior figures from the ISIS affiliate in the Sinai Peninsula, Ansar Bayt al Maqdis, were killed in an airstrike by the country's forces. Egypt is trying to tighten security ahead of next week's visit by Pope Francis following suicide bombings at two Coptic churches on April 9 and Tuesday's attack by ISIS at Saint Catherine's Monastery in the Sinai.
