Sightseers continued to visit Egypt's Sphinx and Giza pyramids just 24 hours after a terrorist bomb attack on a tourist bus killed four people. It was the first deadly attack against the sector in over a year and came as tourism was still recovering from a sharp fall since the country's 2011 uprising.
Three Vietnamese tourists and an Egyptian tour guide died in Friday's attack that took place just 4km from the pyramids.
There was no immediate claim from any group but Islamist militants have been known to target tourists in the past.
On Saturday morning police in Egypt said forty militants were killed in three raids in Giza and North Sinai.
It's not clear if the move was connected with Friday's terrorist attack but the police did say that 30 militants killed in Giza had been planning a series of attacks against state institutions and tourist sites.
