Eleven Israeli Arab tourists were killed on Tuesday and 30 others injured when their bus overturned in Egypt's Sinai Peninsula, officials said, the latest in a string of Egyptian transport accidents, according to Reuters. The officials said the tourists died after the bus flipped on a sharp curve in the road near the holiday resort town of Nuweiba. The Interior Ministry had earlier said an Egyptian tour company employee was killed, but later said all the dead were Israelis. Medical sources said 13 of the injured were in a serious to critical condition. The crash was the third in two days to hit Egypt's transport network. Also on Tuesday, a sleeper train collided with a tractor south of Cairo, injuring two people. On Monday, 58 people were killed in a collision between two commuter trains in Egypt's worst rail disaster in four years.
