MIAMI BEACH, Fla. (WPEC) — Two children were killed and two more were critically injured after a barge struck a sailboat, causing it to sink in Biscayne Bay Monday morning.

According to CBS Miami, around 11:16 a.m., the Miami Beach Police Department (MBPD) received a call for a boating accident involving one adult woman and five youths north of Hibiscus Island. MBPD then dispatched Miami Beach Fire and Miami-Dade Fire to drive in and rescue the victims. All were accounted for within an hour.

All six people on the sailing boat were pulled from the water by responders, and four kids were rushed to a nearby hospital, Jackson Memorial, where two were pronounced dead upon arrival, according to Petty Officer 3rd Class Nicholas Strasburg, a spokesperson for the U.S. Coast Guard.

It was later confirmed that they were participants of the Miami Youth Sailing Foundation. The six were in their last week of the sailing camp for kids from 7 to 15 years old, according to the Miami Yacht Club.

“The entire MYC family is devastated by this terrible tragedy,” said Emily Copeland, the commodore of the yacht club, in a statement.

Miami Beach officers announced that the crash occurred between Monument Island and Hibiscus Island.

Two of the six who were rescued were in “good condition," Strasburg said.

In another update, MBPD said the Florida Fish and Wildlife Commission has taken the lead on the investigation.

The boats collided near Star Island, which runs between Miami Beach and Miami in Biscayne Bay, said Arielle Callender, a regional spokesperson for the Florida Fish and Wildlife Conservation Commission, in a statement.
