2016 Belgium suicide bomb attack: Islamist brothers 'shot dead a man to see what killing was like' before carrying out the attacks

Two Islamist brothers who carried out the devastating Belgium suicide bomb attacks confessed to shooting dead a 76-year-old man at random to see what killing was like, their co-conspirators claim.

Ibrahim and Khalid El-Bakraoui allegedly killed Paul-André Vanderperren, 76, at random in 2014 – two years before carrying out two separate bomb attacks in Brussels killing 31.

Three devastating suicide bombs went off on March 22, 2016 – injuring hundreds of people.
