Six police officers killed in explosion on main road carrying tour buses to Egyptian Pyramids

An explosion on a main road in Cairo has killed six police and wounded another three in what appears to be the deadliest attack on security forces in Egypt in several months.
The explosion took place near a mosque on Pyramids Road, the main avenue leading from the city centre out to the Giza pyramids, which is often used by tour buses, according to the state-run MENA news agency.
