A fire broke out on a charter boat early Monday morning near Santa Cruz Island off coast of Southern California. Five of the crew members from the 75-foot dive boat have been rescued but 34 others are missing.

According to Ventura County Fire Capt. Brian McGrath, there have been fatalities but the exact number has not been released, CBS2 reports.

The Coast Guard reported the boat’s crew members were rescued and “efforts were underway to evacuate remaining passengers.” The Coast Guard was checking to see if any survivors had jumped off the boat or made it to the rocks. Crews were still fighting flames on the boat as of 7 a.m., the fire department said. CBS2 has confirmed Conception is owned by Truth Aquatics, a boat rental and charter service based out of Santa Barbara. According to its website, the Conception has a maximum capacity of 46 people. The company would not immediately comment on the incident when reached by CBS2. Experienced diver and CBS2 employee Darla Fletcher, who has taken several diving trips with Truth Aquatics, explained that the divers’ quarters on the boat are below deck and very cramped. “Typically, the crew members will sleep up top, they’re not gonna sleep down there with the divers,” Fletcher said. “Especially on a full boat like this weekend, there were probably divers filling every possible bunk.” (CBS2)

The Los Angeles Coast Guard tweeted about their rescue efforts this morning, but have not provided any updates for several hours.

President Trump retweeted those messages and appears to be following developments.
