A tourist bus carrying 25 South African tourists was targetted by a roadside bomb near the Giza Pyramids, said media reports.

The blast wounded at least 16 people, including tourists, reports said. Pictures posted on social media showed a bus with some of its windows blown out or shattered, and a shallow hole in the ground near the bus.

The attack comes just as Egypt’s vital tourism industry is showing signs of recovery after years of political turmoil and violence.

No group has claimed responsibility for the attack, reports said.
