At least one man was killed and six people were missing Monday after a luxury superyacht sank near the Sicilian capital of Palermo during a violent storm, Italian officials said. 

The 184-ft sailboat with 22 people on board “suddenly sank” at around 5 a.m. local time (11 p.m. ET) “probably due to the terrible weather conditions,” the City Council of Bagheria said in a statement.

Karsten Borner, the captain of a ship that rescued the survivors, told reporters that there was a “strong hurricane gust and we had to start the engine to keep the ship in an angled position,” according to Reuters.

He added that they had “watched the ship behind us not to touch them and we managed to keep the ship in position.” After the storm was over he said “we noticed that the ship behind us was gone.”

“Fifteen people inside. Four people were injured, three heavily injured and we brought them to our ship, he said. “Then we communicated with the Coast Guard and after some time, the Coast Guard came and later picked up injured people.”

One of the survivors, identified only as Charlotte, told Italian news agency ANSA that she had momentarily lost hold of her 1-year-old daughter Sofia in the water, but she managed to retrieve her and hold her up over the waves until a lifeboat inflated and they were both pulled to safety. immediately hugged her again amid the fury of the waves.
