Russian officials say an overloaded motor boat sank in the Moscow River after crashing into a docked barge in the pre-dawn darkness and nine people were killed. The other seven passengers survived.

Vladimir Markin, the spokesman for the main investigative agency, said the owner had been found in violation of regulations three times in the past, including for exceeding the boat’s maximum capacity of 12. The boat was carrying 16 people when it crashed early Sunday.
