The suspect was placed in psychiatric care after being questioned by police.The man, retired train driver named as William M., told police he had become "depressed" and "suicidal" after his home was burgled in 2016, the office of the Paris prosecutor said on Sunday.The man resented that community because Kurdish militiamen involved in the Syrian conflict had "taken prisoners during their fight against Islamic State instead of killing them", the prosecutors say.The violence unfolded after Kurds had gathered peacefully in the Place de la République to pay tribute to the victims.In the aftermath of the shootings, Kurds have renewed calls to the French authorities for better protection."
