The Belgian city of Brussels has marked the anniversary of the 1985 Heysel stadium disaster.
Thirty-nine people died in the Heysel disaster
Thirty-nine people were killed when fans rioted before the European Cup final between Liverpool and Juventus.
Brussels held a commemoration for the fans, who died when a wall collapsed at the stadium in the city. Of the 39 victims, most were Juventus fans.
"It is this day that the most terrible page of soccer history was written," said Brussels mayor Freddy Thielemans.
A monument was unveiled by mayors from Liverpool and Turin outside the ground on Sunday, with 39 lights set into the ground.
The remembrance came four days after Liverpool beat AC Milan in the Champions League final.
On the new structure built over the collapsed wall, a grey plaque with 39 cuts into its surface reads "In memoriam 29/05/85".
Apart from those killed, more than 400 people were injured in the disaster. Many of the dead were killed trying to escape crowd trouble.
The incident was blamed on hooliganism, and a lack of proper police security. Heysel was later torn down and replaced with the current King Baudouin Stadium.
Liverpool Football Club marked the tragedy when the team met Juventus in April, on its way to winning the Champions League, with a pre-game ceremony at Anfield.
