An Egyptian civilian was shot and killed by unidentified assailants Thursday, taking the number of people killed in 24 hours up to three, a security source told Aswat Masriya news website.

The source said the killing took place in Al-Arish city in the restive Sinai Peninsula.

Egypt has witnessed a wave of militant attacks, mainly targeting security forces but sometimes civilians as well, since the ouster of Islamist president Mohamed Morsi last year.
