A roadside bomb hit a tourist bus on Friday in an area near the Giza Pyramids, killing two Vietnamese tourists and wounding 12 others, Egypt's Interior Ministry said in a statement.
It said the bus was travelling in the Marioutiyah area near the pyramids when the crude roadside bomb, concealed by a wall, went off. The wounded included 10 Vietnamese tourists. The other two wounded were the Egyptian bus driver and the guide.
The bus was carrying a total of 14 Vietnamese tourists, it added, saying only two of them escaped unharmed.
Egypt has battled Islamic militants for years in the Sinai Peninsula in an insurgency that has occasionally spilled over to the mainland, hitting minority Christians or tourists. However, this is the first attack to target foreign tourists in almost two years.
