LONDON, March 23 (Xinhua) -- The cause of a ship toppling over onto its side in a dry dock in Edinburgh, the Scottish capital, remained unclear on Thursday.
The incident happened on Wednesday morning, leaving the ship leaning at a 45-degree angle and at least 33 people injured, according to media reports.
Edinburgh City Councillor Adam McVey said on social media that the vessel had been dislodged by "strong winds."
But Iraklis Lazakis, from the department of marine architecture and engineering at the University of Strathclyde, said in a BBC report that high winds were unlikely to be the cause, adding that it is a very "unusual thing to happen in a dry dock."
The 76-meter vessel is owned by the U.S. Navy. Its previous owner was Microsoft co-founder Paul Allen, according to the BBC.
Fourteen people were still in hospital on Thursday, the Evening Standard newspaper reported.
