Wow people are crazy and getting crazier
Witnesses say a man in his 40s threw grenades at a bus stop in Place Saint Lambert, a busy square. At least two other men are thought to be involved.
Reports say one of the attackers is among the dead. Local media say another has been detained, while a third is involved in a stand-off with police.
It is not clear who the attackers are.
There are reports of a fourth man escaping the scene.
TV images showed blood splattered across the cobblestones.
Medical staff are said to be attending to some of the injured in the courthouse.
Seven of them are in a serious condition, and doctors at a city hospital are trying to save the life of an 18-month-old boy injured in the attack.
