MINYA, Egypt: Egypt launched six air strikes on jihadist camps in Libya on Friday (Saturday in Manila) after masked gunmen attacked a bus of Coptic Christians south of the Egyptian capital, killing at least 28 people. Assailants in three pick-up trucks attacked the bus as it was heading for the Saint Samuel monastery in Minya province, more than 200 kilometers (120 miles) from Cairo, before fleeing, the interior ministry said. It was the latest attack on Copts after Islamic State (IS) group jihadists bombed three churches in December and April, killing dozens of Christians. President Abdel Fattah al-Sisi, in a televised address, said Egyptian forces had hit a jihadist training camp in retaliation. State television reported six air strikes against “terror camps in Libya”, specifying that jihadist training camps were hit in the eastern Libyan city of Derna. Witnesses there reported four strikes by a single aircraft.
