A minute’s silence and vigil were held at midday today following an attack on Christmas shoppers in the Belgian city of Liege.

Four people were killed and around 125 wounded when Nordine Amrani used guns and hand grenades in the attack in the busy Place Saint-Lambert square.

Amrani, 33, was found dead at the scene. City officials said he was not killed by police, while eyewitnesses say he took his own life.

His victims include an 18-month-old toddler, who died last night in hospital as a result of her injuries. A 15-year-old boy was killed instantly and a 17-year-old boy and 75-year-old woman died later in hospital.

The body of a fifth victim was discovered in a warehouse used by the attacker. The woman worked as a cleaner for a neighbour of Amrani.

The minute’s silence and vigil were to be held in the city at midday today.

The square has been reopened to the public but signs of yesterday’s attack remain, with shattered glass and bloodstains still visible.

It is not clear why Amrani carried out the attack. He was reportedly on parole and due to be interviewed by police on Tuesday morning but instead headed to the marketplace where he launched his attack from a rooftop at around midday.

Prime Minister Elio Di Rupo has visited the scene of the attack. He ruled out terrorism, saying it was an “isolated case”.

"The whole country shares the pain of the families affected. We share the shock of the population," he said.

Belgium’s King Albert and Queen Paola II paid their respects at Place Saint-Lambert last night.
