Six people were lightly injured when two drones struck an Egyptian Red Sea resort on the border with Israel on Friday, the army said.

Anarmy spokesperson said on Facebook that an unidentified drone crashed into "a building next to Taba hospital," in the resort town of the same name, just across the border from the Israeli resort of Eilat.

He clarified later that there had been "two drones coming from the south of the Red Sea," which lies off Yemen.

"One fell in Taba and the other was targeted outside Egyptian airspace in the Gulf of Aqaba," with some debris hitting an uninhabited area.

Israel's military said its air force had countered an "aerial threat" and intercepted "hostile targets."

Israeli foreign ministry spokesperson Lior Haiat accused the Iran-backed Huthi rebels in Yemen of firing the drones at Israel.

Earlier Friday, Egypt's AlQahera News television, which is linked to state intelligence, reported "a rocket" falling on Taba "as part of the current escalation in Gaza."

Witnesses had told Agence France-Presse that a rocket hit a hospital annex in the Red Sea resort.

Images circulating online and in Egyptian media showed a damaged building and blown-up vehicles.
