The officer was killed and the soldiers suffered injuries in a roadside bomb attack that hit an area south of the North Sinai provincial capital of el-Arish on Tuesday.
The Egyptian officer, along with the soldiers, was in pursuit of militants in the area when the deadly incident took place.
In another bombing attack that targeted a police base in el-Arish earlier in the day, a civilian was killed and 32 people, mostly police officers, suffered injuries.
“The bomber drove a water tanker filled with explosives into the rear gate of the base,” a security official said, adding, “As the vehicle approached, police fired on it, detonating the explosives inside.”
Egypt’s Interior Ministry spokesman, Hani Abdel Latif, said many of the injured survived thanks to the swift rescue operation by the guards at the site of the first incident on Tuesday.
There was no immediate claim of responsibility, but the Takfiri militant group calling itself Ansar Bait al-Maqdis has claimed responsibility for most of the attacks in the region.
The group has recently pledged allegiance to the ISIL Takfiri terrorist group and changed its name to Velayat Sinai.
A state of emergency has been declared in the northern part of the Sinai Peninsula since a militant attack on an Egyptian army checkpoint killed more than 30 soldiers in October 2014.
The Egyptian military considers the Sinai Peninsula a safe haven for gunmen, who use the region as a base for their “acts of terror.”
Since the ouster of former president, Mohamed Morsi, in July 2013, gunmen have launched terrorist attacks in Sinai, killing Egyptian security forces.
