A Mexican Navy sailboat with 277 people on board crashed into the Brooklyn Bridge Saturday evening, injuring several people on board in a dramatic scene along the New York City waterfront, according to authorities.

       The crash occurred at 8:30 p.m., resulting in at least 19 people injured, according to NYPD.

       Four people were left with serious injuries, according to city officials, who gave a press briefing late Saturday evening.

       Everyone who was injured was on the boat; no one fell into the water, according to officials. Officials said they did not believe the bridge sustained any structural damage.

       There are no fatalities as of now, the officials said.

       The ship was disembarking and heading to Iceland, officials said.

       The National Transportation Safety Board is on site and will begin its investigation, but preliminary information shows it was likely a mechanical issue with the sailboat, according to officials.

       The Brooklyn Bridge had temporarily closed after the crash but has since reopened, according to the New York City Department of Transportation.

       "While inspections will remain ongoing, there are no signs of structural damage to the Brooklyn Bridge," NYDOT said in a statement.
