Four others were injured when armed men opened fire at a security post in the coastal area of northeastern Sinai, which borders the Gaza Strip, the sources said. There was no immediate comment from Egyptian authorities. The deaths follow a May 7 ambush at a checkpoint in Sinai that killed 11 Egyptian soldiers and was claimed by Daesh, one of the deadliest attacks in recent years. Egypt expanded security control over populated coastal areas of northern Sinai since a major counter-insurgency operation was launched in 2018, but sporadic attacks by militants linked to Daesh have continued. News of Wednesday’s attack came as President Abdel Fattah El-Sisi met US national security adviser Jake Sullivan in Cairo. The Egyptian presidency said the two had discussed the strategic partnership between Egypt and the United States, which is a major provider of military aid to Cairo. On Monday, El-Sisi voiced hopes for deeper counter-terrorism ties with Washington in a meeting with the general who oversees US forces in the Middle East, a US military official said.
