At least 17 people were wounded in an explosion that targeted a tourist bus on its way to visit Egypt’s Giza pyramids. The bus was carrying 25 South African citizens when a device exploded near the bus, while the windshield of another vehicle was damaged. Tourists arrived in Cairo airport at noon Sunday and were on their way to visit the Great Pyramids of Giza when the blast hit their bus, a tour guide and one of the tourists told CNN outside Al-Haram Hospital where they were taken. Ten tourists and seven Egyptians were brought to Al-Haram Hospital with minor injuries. Egypt’s Minister of Tourism Rania A. Al Mashat called it a “minor explosion” in a Twitter post. “Of the 28 passengers on the bus we can confirm some minor injuries with three being treated at the hospital as a precaution,” she wrote. South Africa’s government issued a statement on Sunday, saying the Minister of International Relations and Cooperation, Lindiwe Sisulu, had been informed about the incident.
