The Armed Forces recovered a number of small arms, hand grenades, explosive belts, rocket launchers and wireless devices, as well as a quantity of ammunition and high explosives.
The statement added that an injured terrorist was arrested while attempting to escape the hideout.
The Egyptian Army added that legal measures are being taken against him by investigating authorities following his arrest.
This is the latest in a series of raids launched by the Egyptian Armed Forces in North Sinai against terrorist hideouts in May.
On 7 May, the Egyptian Armed Forces announced the death of an officer and 10 soldiers as well as the injury of five others after foiling an attack launched by a group of terrorists on a water lifting station in western Sinai.
A branch of the terrorist group Islamic State (IS) – that was formerly known as Ansar Beit Al-Maqdis – claimed responsibility for the 7 May attack, which was the first major terrorist attack in North Sinai in recent years.
A day after the attack, President Abdel-Fattah El-Sisi directed the Armed Forces during a meeting of the Supreme Council of the Armed Forces (SCAF) to continue purging North Sinai of terrorists.
In 2018, the Armed Forces launched a major counter-terrorism drive dubbed “Comprehensive Operation Sinai 2018” that succeeded in almost eradicating terrorism from North Sinai as well as the Nile Delta and desert areas.
As a result, the rate of terrorist attacks in North Sinai has declined in the past few years following massive and successive security and military operations.
