Tunisia's official news agency TAP says shots have been fired at the country's leading museum, adjacent to the national Parliament building.

The report said the shooting broke out around midday Wednesday at the Bardo Museum. It gave no other details.

Private radio station Radio Mosaique said that three men dressed in military-style clothing may have taken hostages inside the museum. The museum chronicles Tunisia's history and includes one of the world's largest collections of Roman mosaics.

Tunisia has struggled with violence by Islamic extremists since overthrowing a dictator in 2011.
