Cairo: At least 11 civilians were killed and six others injured on Wednesday evening as mortar shells hit two houses in North Sinai province of Egypt, a security source said.
"The mortar shells launched by extremists targeted the armed forces south of Sheikh Zuweid city but they mistakenly hit the said two houses," the source told Xinhua.
Meanwhile, five militants were killed during clashes with security forces in the province as part of the security raids on militants' hideouts in the peninsula.
Sinai-based Ansar Bayt al-Maqdis(ABM), which has recently pledged allegiance to the Islamic State(IS) regional militant group, claimed responsibility for most of the anti-government attacks in Egypt.
