Egyptian troops killed nine militants and arrested several other suspects in Rafah on Wednesday, state news agency MENA reported.
The nine militants were killed during a raid of a hideout in the North Sinai border town of Rafah, MENA added.
Ten other suspects were arrested during raids on the towns of Rafah and Sheikh Zuweid, where most of the recent deadly attacks by militant extremists have taken place.
Army spokesman Mohamed Samir published early Thursday a photo of what he said were ammunitions and explosives seized by Egyptian forces during a separate raid in Barth in central Sinai.
Egypt's army has been fighting an insurgency in parts of North Sinai, which has resulted in the deaths of hundreds of militants and security forces.
