On 13 December 2011, a murder–suicide attack took place in the city of Liège in the Wallonia region of Belgium.

[2] The attacker, 33-year-old Nordine Amrani,[3][4] threw grenades and fired an FN FAL[5] rifle at civilians on the Place Saint-Lambert, the city's main square.

The gunman then fired shots with a 7.62×51mm NATO FN FAL from the rooftop of a bakery shop, located across the square.

The conviction was for possession of thousands of weapons parts, almost 10,000 rounds of ammunition, dozens of weapons, including a rocket launcher, assault and sniper rifles, as well as 2,800 cannabis plants, in the context of a criminal conspiracy (association de malfaiteurs).

He also had convictions for handling stolen goods and sex offences but had no known links to terror groups.

[15] On the day of the attack, Amrani had been summoned for an interview with the police to answer questions about a sexual abuse case.

After the murder, he hid her body in his shed, then left his flat for the city centre, equipped with a backpack containing the weapons.

"[19][20][21] Albert II, King of the Belgians, was shocked and visited Liège on the same day, along with Queen Paola.

[19] Condolences were expressed by the governments of Australia,[23] Estonia,[24] Latvia,[25] Lithuania,[26] Luxembourg,[27] Singapore[28] and the United Kingdom.
