Nearly 900 Liverpool fans caught up in the chaotic scenes at last year's Champions League final are to sue Uefa, say lawyers.
A recent independent report found Uefa bore "primary responsibility" for what almost led to a "mass fatality catastrophe" in Paris last May.
Fans were penned in and sprayed with tear gas outside the Stade de France as kick-off was delayed by 36 minutes.
Law firm Leigh Day has issued Uefa with a group personal injury claim.
The Liverpool-based firm issued the claim on behalf of 887 clients at the Liverpool District Registry of the High Court on Monday.
