A roadside bomb blast took place near the Giza pyramids.
Egyptian police killed 40 "terrorists" in separate raids early Saturday, a day after a roadside bomb near the Giza pyramids killed three Vietnamese tourists and their guide, the interior ministry said.
Two raids in the Giza governorate killed 30 "terrorists", while the remaining 10 were killed in the restive North Sinai, the ministry said in a statement.
It said authorities acted after receiving information the suspects were preparing a series of attacks against state and tourist institutions and churches.
