Four people were killed and more than 100 people were injured Tuesday when 33-year-old Nordine Amrani began shooting shoppers at a busy downtown square in the town of Liege. He also threw several grenades into a bus shelter.
Police searching Amrani's apartment found the body of a cleaning woman.
Amrani died in the attack in an apparent suicide. Two male teenage students, 15 and 17 years old, also died in the attack, while an 18-month-old toddler died Tuesday evening in a hospital, Liege police said.
Several of the wounded victims were still in intensive care on Wednesday.
Officials still don't know the motive for the attack.
