The ministry said the accident occurred at 1:00 pm local time (0900 GMT) near the town of Naro-Fominsk, about 80 kilometres (50 miles) southwest of Moscow, as the passenger train was travelling from the Russian capital to Moldova's capital Chisinau.

Russian Railways said in a statement that 16 wagons of the freight train had derailed, damaging at least two carriages of the passenger train.
