The Egyptian military has yet to make a statement confirming the incident.

The Sinai Peninsula, which shares a land border with Israel, has often been the site of attacks targeting Egyptian security forces stationed there.

Sinai, located in northeastern Egypt, has suffered from an Islamic State group and Al-Qaeda-linked insurgency for over a decade.

It intensified in 2013 following the removal of elected President Mohamed Morsi in a military coup led by current Egyptian President Abdel Fattah al-Sisi.

The attacks are largely confined to the northern part of the peninsula, and have not expanded to its southern region, which is popular with tourists and visitors.

Though there is no official death toll, hundreds of security personnel, civilians, and militants have been killed in similar incidents over the years.
