The early morning attack took place in the North Sinai provincial capital of El-Arish, the officials said.
Militants have stepped up attacks in the peninsula since the army’s ouster of Islamist president Mohammed Morsi in July 2013.
“The bomber drove a water tanker filled with explosives into the rear gate of the base,” a security official said.
“As the vehicle approached, police fired on it, detonating the explosives inside.”
