Atletico Nacional's Copa Libertadores celebrations leave four dead
Celebrations in Colombia after Atletico Nacional won the Copa Libertadores final on Wednesday ended in violence, with four fans killed in a night of boisterous revelry.
Authorities say they registered more than 600 street fights after Medellin's Atletico Nacional defeated Ecuador's Independiente del Valle 1-0.
It was Nacional's second-ever title in the premier South American club tournament and the first by a Colombian team since 2004.
One of those killed was wearing the shirt of a rival Medellin club when he was slashed in the neck with a knife.
There were also reports that mobs of Nacional fans attacked adversaries in Bogota.
Police say at least 23 people were injured.
