Reports are coming in of an accident on HMS Belfast. Photos from the Thames attraction appear to show that the main gangway has collapsed into the river. The walkway had been undergoing repair. The cause of the collapse is not yet clear.
There are no reports of any injuries at this time, but we'll update this post as more information comes in.
Update 14:25 We've now received the following statement from Imperial War Museums, who operate the attraction.
The gangway which leads visitors onto HMS Belfast has collapsed. Two contractors working on the site have sustained minor injuries and have been taken to hospital as a precaution.
We are currently evacuating the ship and arranging for boats to escort all visitors and staff back to shore to the nearest pier. The Port of London Authority and emergency services have been informed.
The ship will be closed until further notice. We are beginning an urgent and full investigation into what has happened. At the moment our priority is ensuring all our visitors are safe.
