Heart attack claims 'visionary' IOC official

Tributes flowed on Monday for Switzerland's Patrick Baumann, the secretary general of basketball's world governing body who died of a heart attack on Sunday in Buenos Aires.

Baumann was working at the Youth Olympics in his role as president of the Association of Summer Olympic International Federations and an International Olympic Committee (IOC) member. He was 51.

"Basketball has lost a leader, an advocate and a friend and our thoughts are with Patrick's wife and two children at this tragic time," the International Basketball Federation (FIBA) said in a statement.
