The Israeli military said on Wednesday it shot down a drone that was carrying weapons and crossed from Egypt to Israel.
When asked about the latest drone incident, Egyptian security sources said they had no knowledge of such an incident.
In two separate incidents in October, Israel also said it downed two drones smuggling weapons from Egyptian territory.
Israeli officials have said during the war in Gaza that the Palestinian terrorist group Hamas used tunnels running under the border into Egypt's Sinai region to smuggle arms.
However, Egypt says it destroyed tunnel networks leading to Gaza years ago and created a buffer zone and border fortifications that prevent smuggling.
