A pleasure boat has sunk on the Moscow River in Russia's capital, drowning nine people, officials say.
Seven of the 16 on board were rescued, they said. The boat is reported to have been hosting a birthday party and is suspected to have been overcrowded.

Reports say the boat, the Swallow, collided with a barge in the early hours of Sunday morning.
The accident comes three weeks after a tourist boat sank on the Volga river in Tatarstan, killing more than 100.

The Deputy emergency minister Alexander Chupriyan said: "After the collision, the motor boat was pulled under the bottom of the barge."
The accident took place close to the city's Luzhniki sports stadium.
Yury Besedin, an emergency ministry official, told local television the accident was "provisionally believed to have taken place because of breaches of shipping rules".
Three weeks ago the 80m (260ft) Bulgaria - a double-decker river cruiser built in 1955 - listed during a thunderstorm on the Volga river and sank in minutes, trapping many passengers inside.
About 80 people were rescued.

Officials said the boat was designed for 140 passengers and crew but it had been carrying 208 people. It also lacked the correct licences and one of its engines was not working, prosecutors said.
Russian police arrested the director of the company that rented the boat and a ship registrar who certified it.
