At least two people have been killed and another 12 injured after a roadside bomb exploded near a bus carrying Vietnamese tourists close to the pyramids in Giza, Egypt. Reuters reported that the device was hidden near a wall on Marioutiya Street on the Cairo outskirts. An Egyptian security source told The Guardian the bus had 14 people on board and an IED exploded as it approached. Two Egyptians, a driver and a tourist worker, were reportedly among the injured. Injured individuals were transferred to nearby hospitals. Egypt has intensified its security presence around churches this month in anticipation of any attacks against the Coptic minority—which make up the majority of Egypt’s roughly 9 million Christians.
