Egyptian police have arrested three people suspected of involvement in Sunday’s blast in Cairo which killed one person and wounded at least 20. Another bomb was found shortly afterwards and detonated safely.Newspapers on Monday morning condemned the attack in the capital’s bazaar which was packed with tourists, calling it “cowardly.” One eyewitness described it as a big explosion: “I saw two tourists with blood on them. They were taken to hospital. We thought those bombs would never explode in Egypt again,” said Abdel Hamid. The victim was a 17-year-old French girl on a school trip. Most of the injured were French tourists. There were also Saudis, a German and four Egyptians among them. The blast on Cairo’s bustling main plaza at the Khan el-Khalili bazaar was the first attack on tourists in three years. Some believe it could have come in response to Egypt’s efforts to help broker a ceasefire in the Middle East between Israel and Hamas. Around 50 French teenagers who were on the same school trip as the girl who was killed have now returned home to Paris. Relatives of the remaining 15 schoolchildren still in Egypt have been flown out to Cairo.
