Nephew of Berlin truck attack suspect arrested

The nephew of Berlin truck attack suspect Anis Amri and two other men have been arrested on suspicion of belonging to the same extremist network.

Tunisia's Interior Ministry said that Amri - suspected of driving a lorry into a Christmas market crowd, killing 12 - had sent his 18-year-old nephew Fedi money to join him in Europe.

It is unclear whether the suspects helped Amri flee Berlin.

The nephew was arrested in Amri's home town of Oueslatia while the others were arrested in Tunis.
