At least one Egyptian police officer has been killed and another injured in an attack by armed men against their patrol vehicle in Egypt’s central province of Giza, Press TV reports.

The two officers were attacked in the el-Baragil district of the province during the early hours of Tuesday.

No individual or group has claimed responsibility for the assault, yet. Security forces have launched an investigation into the attack, and a search for the assailants is under way.

The development came more than a week after two policemen were injured in a bomb blast near an Egyptian Foreign Ministry building in the Agouza district of Giza.

On September 26, at least two policemen were killed and over a dozen others injured in a roadside bomb explosion just outside the city of el-Arish, located about 344 kilometers (214 miles) northeast of the capital, Cairo.

The Egyptian military has been engaged in operations to quell acts of terrorism and militancy in the Sinai Peninsula. It views the volatile region as a sanctuary for extremists, who use the terrain as a safe haven.

The militant group Velayat Sinai, previously known as Ansar Bait al-Maqdis, has claimed responsibility for most of the attacks in Sinai. Last November, the group pledged allegiance to the Takfiri Daesh terrorist group, which is mainly operating in Iraq and neighboring Syria.
