TUNIS, Tunisia (AP) -- A top Tunisian security official says two extremist gunmen who killed 21 people at a top museum in Tunis trained in neighboring Libya before carrying out the deadly attack.
Rafik Chelli, the Interior Ministry's top security official, said the attackers had slipped out of Tunisia in December and received weapons training in Libya before returning home. He told the El Hiwar El Tounsi TV channel that authorities did not have details about where or with which group they had trained.
Wednesday's attack at the National Bardo Museum killed 21 people, 17 of them cruise ship tourists. The two gunmen were killed in a firefight.
The Islamic State group based in Iraq and Syria has claimed responsibility. Several well-armed groups in Libya have pledged their allegiance to Islamic State.
