Al Qaeda issued a statement denying any involvement to the terrorist attack in a Marrakesh cafe in late April. The group nonetheless urged Moroccan Muslims "to liberate their oppressed, jailed brothers and to topple the criminal regime." Moroccan police have arrested three people believed to be involved in the attack, and alleged the chief suspect to be a member of al Qaeda, saying he had disguised himself as a harmless, guitar-strumming entertainer before planting two bombs in the popular cafe. Mostly tourists were affected by the bombing, which killed 17 people and injured 20 more. After the release of al Qaeda's statement, hundreds gathered outside of the cafe on Saturday to protest against terrorism.
