Russia was observing a day of mourning after as many as 110 people died when an overloaded boat sank on the Volga. Some 50 children were said to be among those who drowned when the Bulgaria, a tourist boat, sank on Sunday, according to the BBC. Around 80 people were rescued on the wide section of the river in Tatarstan, 750km east of Moscow. Some 50 bodies have been found. Officials say the boat’s capacity was 120 passengers and crew, but it had been carrying 208 people. A 50-strong team of divers had been scouring the sunken boat in the murky river for survivors, and seen about 50 bodies – most of them children – trapped in a recreation room on the sunken vessel, emergency ministry officials said.
