Two men have been arrested in Germany on suspicion of planning an attack on a shopping centre in Oberhausen near the Dutch border, police say, the BBC reports.

The brothers, aged 31 and 28 and born in Kosovo, were detained early on Friday in Duisburg.

Germany is on high alert after Monday’s attack in Berlin, which left 12 dead.

A Europe-wide manhunt continues for Anis Amri, the Tunisian man suspected of driving a lorry into the Breitscheidplatz Christmas market.

Police said the Oberhausen attack had been intended to target the CentrO shopping centre.
