Floods in Romania killed 20 people in the past week, with thousands left homeless and dependent on army airlifts for food and drinking water, authorities said on Sunday. The deaths took the toll in the Balkan state's worst floods in half a century to 26 this month. Torrential rains have swollen rivers, flooded homes and churned up roads, hitting the eastern part of the country of 22 million particularly hard. Reuters quoted Prime Minister Calin Tariceanu as saying that emergency aid had been airlifted by the army to stranded villagers and floodwater had started to be pumped away.
