The second fire in ten days broke out at the ill-fated Sergei Abramov river boat moored in Moscow, and was put out shortly after midnight Tuesday Moscow time, an emergencies service spokesman said.
Another fire broke out late on Wednesday during post-fire works, presumably when flammable isolation materials caught fire during welding. It spread to an area of about 20 square meters.
"At 00:15 the fire was extinguished, no casualties reported," a spokesman for the Moscow rescue service, Yevgeny Bobylyov, said.
The three-deck river boat Sergei Abramov caught fire early on November 14. Four people on board were injured and one crewmember is still missing.
According to a preliminary investigation, the fire might have been caused by defective electric wiring or fire-safety violations.
The incident is one of a string of serious accidents involving Russian riverboats in recent months. The worst incident was the sinking of the cruise ship Bulgaria, which went down in a storm in the Volga River in the Republic of Tatarstan on July 10, killing 122 people.
