Tunisia Museum Attack: Suspect Arrested in Italy

Italian police have arrested a man suspected of taking part in the attack on Tunisia's national museum which killed 22 people, mostly tourists.

Police said they arrested a Moroccan man who Tunisian authorities suspect of involvement in the raid on the Bardo museum in Tunis in March.

It is not clear what his alleged involvement is.

Tourists from Germany, Poland, Italy and Spain were among those killed when gunmen opened fire at the museum.

They stormed the building and took hostages. Two of the gunmen - identified by the authorities as Yassine Laabidi and Hatem Khachnaoui - were killed by security forces.

Italian media said a 22-year-old man was arrested in Milan who had been wanted on an "international level".

Islamic State has previously said it was behind the raid.

In the days after the attack, Tunisian authorities arrested a number of people.

At the end of March, they claimed to have killed the alleged leader of the assault, Lokman Abu Sakhra.
