Haiti's government cancelled the last day of carnival and announced three days of mourning on Tuesday after 16 people were killed and 78 injured when a carnival float hit a power line in the capital Port-au-Prince, setting off a stampede by bystanders, officials said.

Amateur video of the incident posted on YouTube showed the electric cable catching a popular singer known as Fantom on the float as it passed near the presidential stand packed with spectators. Most of the victims were trampled to death in the ensuing panic.
