Gun violence erupted during yesterday's West Indian Day parade in New York City, leaving two people dead and two police officers wounded, according to area media. What began as a conflict between two armed men quickly escalated into a shootout with police around 9 p.m., and police initially said both gunmen were killed, along with an innocent bystander.

In revised reports Wednesday morning, police said they were misinformed about the death of one gunman. The shooter's motives remain uncleaer, but the West Indian Day parade has been marked by a history of violence.

NYC Mayor Michael Bloomberg has blamed Washington for not taking bold action against "illegal firearms."
