Residents heard a large explosion Friday in the region near the border with Israel. The officials told the Associated Press on condition of anonymity that the attack was in cooperation with Egyptian authorities.
The Israeli military said they are looking into the report.
Egypt’s military and security forces are engaged in long battle against Islamic jihadists in the largely lawless peninsula.
On Thursday, Israel briefly closed an airport near the border after Egyptian officials say they warned of possible militant rocket attacks.
Israeli Air Force jets shot down a drone that entered Israeli airspace.
The unmanned aerial vehicle entered Israeli airspace from the Mediterranean Saturday morning. It was intercepted and shot down over the northern Negev in an unpopulated area, according to the Israel Defense Forces.
IDF Spokesperson Brig. Gen. Yoav Mordechai said that the aircraft was identified before entering Israeli airspace and was downed in accordance with a decision of the IDF's top leaders.
