Egyptian air defense shot down a suspected drone off the Red Sea coast near the resort town of Dahab on Egypt's eastern Sinai coast, two security sources said.
The security sources said the drone's origin was unknown.
Witnesses in Dahab said they saw an object fall into the water. They said they saw another flying object fall in the nearby mountains.
In late October, drones caused explosions that rocked two other Red Sea towns, which Israel said Yemen's Iranian-backed Houthi movement sent them to strike its territory.
