Egyptian authorities uncovered a munitions cache, including antitank weapons, buried in the sand of the Sinai Peninsula near the border with Israel, a security official said Monday.
The discovery took place when a large security force raided the town of al-Jora in the northern Sinai on Monday, the Palestinian news agency Ma’an reported.
The weapons were found in an underground storage room about five kilometers from the Israeli border and included 15 antitank mines, grenades and other weapons.
Egyptian security forces have been working to return law and order to the peninsula, which is thought to be home to several terror cells working to smuggle weapons into Gaza.
The find is a the latest in a series of operations against Islamists harboring heavy arms, many of which trickled in from Libya.
In February Egyptian authorities intercepted a truck carrying two tons of explosives that was heading for the border with Gaza, where the contents were apparently to be smuggled into the coastal enclave.
Earlier in the month Egyptian security officials claimed to have foiled five attempts to smuggle weapons from Sinai into Gaza in the previous weeks. In January another truck carrying a ton of explosive was seized as it headed from Cairo to Sinai.
The effort to clean up the peninsula was sparked by an attack on an Egyptian army position in Rafah last year that left 16 border guards dead.
In January, seven Egyptian policemen were injured in an ambush by Islamic terrorists.
