Two women have been killed and three policemen injured in two separate attacks in Egypt’s Sinai Peninsula, Press TV reports.

The women were killed in the first incident in the northern Sinai town of Sheikh Zuweid on Tuesday, when an errant shell reportedly landed on their house. Four other people were also injured.

Separately, local Egyptian security sources confirmed that at least three policemen were injured, one of them seriously, when their armored vehicle was hit by a remote-controlled bomb in the city of el-Arish.

On October 3, at least two Egyptian policemen were killed when gunmen opened fire on them in the region. The Egyptian Interior Ministry said in a statement a day after that “a police captain and a policeman died of their wounds after unknown assailants shot them.”

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 terrorists.

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 Syria.
