An explosion hit a bus carrying South African tourists while it was on the move near the Pyramids, injuring at least 14 people.
According to a security source, a device exploded near the bus – which was carrying 25 tourists from South Africa – shattering the bus windows and injuring many of those on board.
The blast also hit a nearby car, injuring four Egyptians.
The attack comes nearly five months after three Vietnamese tourists and their Egyptian tour guide were killed when a bomb hit their tourist bus as it was traveling on El-Maryoutiya Street in Giza s Haram district.
No group has claimed responsibility for the December attack.
Egypt has responded to terrorist attacks over the past few years with raids on terrorist hideouts nationwide, including a concentrated offensive in North Sinai to combat terrorism.
