GELENDZHIK, Russia — Russian President Vladimir Putin ordered investigators to find out whether local officials could have done more to prevent floods killing 150 people in southern Russia after flying to the region to handle the first big disaster of his new presidency. Putin, who was criticized for his slow reaction to disasters earlier in his career, has promised money for new homes for victims of the worst flooding in decades in Krasnodar, a prosperous region with thriving agriculture and tourism. He declared Monday a day of mourning for the dead, most of whom drowned. Many were elderly people caught unawares as they slept when water swept through their homes after two months' average rainfall fell in a night. “I have asked the leadership of the (federal) Investigative Committee to come down,” Putin said late on Saturday during a meeting with officials in Krymsk, the worst-hit town. “The Investigative Committee will check the actions of all the authorities - how notice was given, how it could have been given, how it should have been given and who acted in what way.” Police said survivors climbed into trees and onto roofs to stay above the waters, which flooded entire ground floors of some buildings and created driving torrents in some streets. — Reuters
