Bees swarm around Muhammad Ali Center in Louisville

Thousands of bees have swarmed around the Muhammad Ali Center in Louisville, Kentucky, as mourners gathered to remember the boxing champion.

The former heavyweight champion famously said he could "float like a butterfly and sting like a bee".

Kevin McKinney, a specialist from the Kentuckiana Beekeepers Association, who came to collect the bees, said they had "picked a pretty good spot".
