At least 17 people including tourists have been injured in an explosion near Egypt’s pyramids in Giza.
A device went off close to the Grand Egyptian Museum as a bus carrying tourists was passing.
It has been confirmed that among the injured were seven South African tourists and 10 Egyptian civilians. The bus was carrying 28 passengers.
The BBC said it is not yet known who was responsible for the attack, but Islamist militants are suspected having previously targeted tourists in Egypt.
Pictures on social media show a bus with some of its windows blown out or shattered, and debris in the road, Sky News reported.
Maryland Tours had rented the bus from Dominant Travels. A spokesman told Sky News the injuries were not serious.
The attack is the second incident affecting tourists in Egypt in six months.
Three Vietnamese tourists and a local tour guide were killed after a roadside bomb hit their bus in December.
Aito said the attack was a “setback” for Egypt but urged the trade to get behind the destination.
Derek Moore, Aito chairman, said: “There is no doubt that it’s a setback for Egypt but it’s important to remember that this attack is in an area that represents but a small section of the enormous range of cultural treasures and sites of what is a large country.
“The resilience of destinations is very encouraging. In the last year we have seen terrorist attacks in tourist destinations such as Indonesia, Belgium, Jordan, Holland, Egypt, Australia, Morocco, Kenya, New Zealand and Sri Lanka. Unless there is a subsequent FCO travel advice warning against ‘all but non-essential travel’, by and large – in Aito’s experience, these destinations have bounced back remarkably quickly.
“I am confident that the Egyptian authorities are doing everything they can to minimise the chance of any repeat incidents; they understand, of course, the vital need to give confidence both to visitors and to the governments of those countries from which tourists travel to visit Egypt.”
Aito has 12 member companies which organise trips including: Abercrombie & Kent, Classic Collection Holidays, Cyplon Holidays, Discover Egypt, Dragoman, Enable Holidays, Explore, Imaginative Traveller, Oasis Overland, On The Go Tours, Specialist Journeys and The Travel Department.
