Russian President Vladimir Putin has demanded an investigation into the emergency response to flash floods in the southwest of the country after at least 150 people were killed. Floods and landslides have devastated the Krasnodar region after two months' average rainfall fell in a few hours. The number of confirmed dead has risen to 150, according to Reuters news agency. Television footage showed torrents of brown floodwater gushing along streets in the worst-hit town of Krymsk past blanket-covered bodies. Mr Putin was flown over the region by helicopter before a brief meeting with local officials in Krymsk, amid claims by residents that authorities had abandoned them. The president ordered investigators find out whether local authorities had given people enough warning to get to safety.
