Ibrahim and Khalid el-Bakraoui grew up in Laeken, a working-class neighborhood in northwest Brussels, not far from the Royal Palace. Their father, a retired butcher, is a devout Muslim who emigrated from Morocco; their mother is conservative and reclusive. Just two years apart in age, the brothers shared burly features, and, by their mid-20s, had amassed a formidable record of violent crime.
Belgian investigators are racing to assemble a fuller portrait of the brothers who — along with at least two accomplices — carried out the suicide attacks in Brussels on Tuesday that killed 31 people.
