A civilian was killed on Tuesday in North Sinai's Sheikh Zuweid city by unidentified assailants, state news agency MENA reported.
MENA said the man, 37, was shot in the head by militants who stole his car.
The corpse was transferred to Al-Arish General Hospital and police are investigating the incident.
Egypt's army has been waging a major offensive against Islamic insurgents in the northern part of the peninsula.
The army has targeted militant hideouts with helicopters and ground troops, killing dozens in recent months.
However, news reports have surfaced over the past months claiming that civilians too have been caught in the crossfire.
At least six decapitated bodies of civilians, reportedly killed by militants, have been found in North Sinai in the last month.
