Four Egyptian policemen were killed and six others were injured in two blasts in North Sinai, Al-Ahram Arabic news website reported.
According to security sources and eyewitnesses, unidentified assailants planted an improvised explosive device (IED) on a north Al-Arish road. The IED then detonated while a police vehicle was passing, killing a first lieutenant and a first sergeant and injuring three other police members.
In another blast, a brigadier general and a conscript were killed, and three other conscripts were injured after an IED exploded in Al-Montabh in central Sinai when an IED targeted a patrolling police vehicle.
No group has yet claimed responsibility for the attacks.
The two attacks come only one day after Egypt's army announced both the army and police forces were able to successfully thwart an attack that was set to target a security checkpoint in the North Sinai city of Sheikh Zuweid.
The latest announced operations against militants come in continuation of the security forces' Operation Martyrs' Right, a comprehensive joint military and police operation that started in September 2015.
