A toddler died after falling into a sewer when a pavement gave way in the western Russian city of Bryansk on Sunday.
Local police and emergency services said a burst water pipe had caused the pavement to collapse under the one-and-a-half-year-old boy's mother, who was pushing him in a pram.
A passer-by was able to rescue the mother from the hole, but the child was swept away by the rushing water, officials told the Itar-Tass news agency.
Russian infrastructure is notoriously unreliable, having suffered from a chronic lack of investment since the fall of the Soviet Union 20 years ago.
