Children In Danger?
Spain's Palm Marroca's Maritime Rescue spokesman Miguel Chicon told RadarOnline.com that while he couldn't confirm what children were onboard the yacht, that children were present during the fire.
"There was a yacht heading towards Mallorca. This was yesterday around two o'clock in the morning when we were first called. There was a fire in the engine room," Chicon told RadarOnline.com. "The crew themselves, they called us asking for help. We sent our rescue boats."
"While they were extinguishing the fire by themselves, the fire was under the control by the time we arrived," Chicon continued.
"We arrived there with our rescue boat and we towed the ship to port Adriano, which is a port southwest of Mallorca island. Once we were there, we had to call the firemen to wait for the ship upon arrival just in case. The firemen went to the engine room to make sure everything checked out."
Fortunately no one was hurt, according to the spokesperson.
"All the members on board didn't need assistance. We did send ambulances, but there was no need for an ambulance at all, they were all safe. We know there were nine people on board, some were children, but I don't know who specifically."
During Klitschko's video, a flood of rescue personnel can be seen on the Yacht manning the ship.
