FOUR PEOPLE have been killed and 75 others injured in a grenade attack in Liege, Belgium at around 12.30pm local time today.

According to 7 Sur 7, the attack targeted the central Place Saint-Lambert square near a busy Christmas market.

Early reports suggested that three people were involved in the attack, however police said this afternoon that they believe one man identified as Nordine Amrani carried it out by himself.

An official said that the attack today is not believed to be linked to terrorism.

The four people killed include a 17-year-old boy, a 15-year-old boy and a 75-year-old woman, as well as the suspected attacker. A two-year-old girl is understood to be critically injured.

Belgian officials say that the gunman who died at the scene was armed with more grenades and that he has a criminal record for offences involving guns, drugs and sexual abuse. They said was on his way for police questioning at the time of the incident.
