Projectiles hit two Egyptian Red Sea towns on Friday injuring several people, sources and officials said, showing the risk of regional spillover from the Israel-Gaza conflict.
The explosions hit Taba on the border with Israel and Nuweiba about 70 km (43 miles) further away, two Egyptian security sources told Reuters, saying they were still gathering more information.
There was no claim of responsibility, but Egypt's state-linked Al-Qahera News said the missile that hit Taba appeared to be connected to fighting between Hamas militants and the Israeli military around Gaza, about 220 km (137 miles)miles away.
Egypt's health ministry said six people were injured in Taba, with four already discharged from hospital, after an ambulance facility and residential building were hit.
Witnesses in both places, who asked not to be named, confirmed explosions and smoke rising. Israel's military said it was aware of a security incident outside its borders.
Taba and Nuweiba, both in Egypt's Sinai Peninsula, are popular with tourists.
Last weekend, several Egyptian border guards were also injured after being accidentally hit by fragments of a shell from an Israeli tank. Israel apologized for the incident.
