Bomber kills himself, one other at Sinai checkpoint - sources
The attack occurred in El-Tur, a town on the main road between Cairo and the tourist resort of Sharm El-Sheikh.
In a separate attack on Friday, a bomb injured at least three Egyptians when it went off near a tourist bus being used to transport workers further south on that road, security sources said.
