Six people held over Brussels New Year's Eve attack plot

Belgium's federal prosecutor has said six people have been detained during house searches in Brussels in relation to an investigation into a plot to carry out an attack on the city on New Year's Eve.

A judge is set to decide on Thursday whether they can be held further.

On Wednesday, Brussels cancelled its New Year's festivities and fireworks display due to the threat of a terror attack.

The city's Mayor Yvan Mayeur said the decision was taken following a risk analysis by its crisis centre.

"In these circumstances, we can't check everyone," Mr Mayeur told the French-language RTBF network.

Two other people arrested earlier this week will be held for a month after being charged with threatening to carry out a terrorist attack, prosecutors said.
