Police in Mali have placed two individuals under arrest for their role in a recent terrorist attack on a luxury hotel that left 20 dead. The two gunmen—who stormed the Radisson Blu hotel on Nov. 20 and opened fire on guests—were both killed during a raid a on the building, but may have been working with others to plan the attack. Officials haven’t yet said what role the two individuals played in the terrorist attack, but issued a statement, explaining, “Questioning of these suspects will shed more light on the motivations of the perpetrators of the sordid terrorist attack perpetrated.” Two different groups in the country claimed responsiblity for the mass shooting: a radical Islamic group linked to al-Qaida called the Al-Mourabitoun, as well as, a militant group known as the Macina Liberation Front.
