CAIRO (AA) - At least three people were killed Saturday and four others wounded in a bomb attack in Egypt's Sinai Peninsula, according to local security sources.
All of the casualties were civilians in the attack in the North Sinai city of Arish, the sources said.
No one has yet claimed responsibility for the attack.
Since Mohamed Morsi, Egypt's first freely-elected president, was ousted in a military coup in 2013, Egyptian security forces have waged a fierce campaign in Sinai against what they describe as "terrorist groups".
The campaign, which involves police and army forces, has been accompanied by frequent attacks on security personnel deployed in the restive peninsula.
Authorities say they are battling the Welayat Sinai, or Sinai Province group, which is said to have sworn allegiance to the Daesh terrorist organization.
