At least 11 children and one adult have drowned after three tourist vessels were caught in a lake storm in Karelia, northwest Russia, the Investigative Committee said. All the children were from Moscow, Mayor Sergey Sobyanin said, citing preliminary data.

"There has been a great tragedy in Karelia," Sobyanin said. "According to the preliminary data, 10 children from Moscow have died on Lake Syamozero. Condolences to the families and friends [of the victims]," the mayor wrote on Twitter.

The tourist group that got caught in the storm consisted of two boats and one raft, according to information from the Emergencies Ministry. Rescuers have managed to save 11 people so far, the ministry said in a statement.

There were 47 children and 4 adults on board the three tourist vessels, Investigative Committee spokesman Vladimir Markin said in a statement.

Only those children who were in life vests managed to survived, children's rights ombudsman Pavel Astakhov wrote on Twitter.

The children were from a summer camp located near the lake.

One girl reportedly managed to reach the shore of the local resort by herself.

Moscow authorities are sending rescuers, doctors, psychologists and social workers to the scene.

The head of the Republic of Karelia, Alexander Khudilaynen, is also heading there.
