A man has been arrested in Belgium after he was accused of threatening passengers on a train with an 11-inch blade while shouting 'Allahu Akbar'.

Eyewitnesses reported hearing the man ranting on the train and he is alleged to have shouted: 'Allahu Akbar' and 'We're going to kill all of you'.

Police were waiting for the suspect on the platform as the train arrived at Brussels-South.

There have been a spate of terror attacks in Belgium in recent months. In August, a knifeman was shot dead in Brussels after attacking a group of soldiers.

And in March 2016 35 people were killed and more than 300 were injured in the Belgian capital when suicide bombers attacked the airport and Maalbeek metro station.
