A special court will try the brother of Mohamed Merah, who killed seven people in a murderous spree in the French city of Toulouse in 2012, for complicity in the attacks, judicial sources said Wednesday, according to AFP.

Merah, a self-described Al-Qaeda sympathizer who had traveled to Afghanistan and Pakistan, shot dead three Jewish schoolchildren, a teacher and three soldiers in Toulouse and nearby Montauban in a nine-day killing spree in March 2012.

His brother Abdelkader, who had been under closer scrutiny by intelligence services than Mohamed, claimed he was unaware of the plans for the attacks, which prompted stepped-up surveillance of suspected Islamic terrorists.
