An attack on a bus carrying Vietnam tourists has once more raised concerns about the safety of travellers in Egypt.
Last Friday, three Vietnamese tourists and an Egyptian guide were killed and at least 10 others injured when a roadside bomb blast hit their tour bus less than four kilometres from Egypt's world-famous Giza pyramids.
In response, Egyptian security forces have killed 40 suspected militants. The ministry of interior said "terrorist elements" were planning a series of attacks targeting state institutions, the tourism industry and churches.
Security is currently tight in Egypt, with the tourist season at its peak and the country's main Christian minority, the Copts, preparing to celebrate Orthodox Christmas on January 7.
Tourism peaked in 2010, when Egypt saw more than 14 million visitors, but fell sharply after the turmoil of the Arab Spring the following year. The sector has since recovered, although not to former heights with 8.3 million visitors in 2017, the Financial Times reports.
