US Nuclear sub has hit an unknown object in the South China sea
11 sailors are reported injured but it is still operational and heading for Guam.
According to AP, the officials said the object the USS Connecticut collided with was not another submarine. One of the officials quoted by the agency said it could have been a sunken vessel or container, or other uncharted object.
Alex Neill, a Singapore-based defence and security expert, told the BBC the number of injuries caused by the collision suggested the submarine probably "hit something big" and was "going really fast".
Meanwhile, the US National Security Advisor, Jake Sullivan, told the BBC he was "deeply concerned" about actions that undermine peace across the Taiwan Strait, which separates Taiwan and China.
He was speaking after China sent a record number of military jets into Taiwan's
air defence zone for the fourth day running.
