Floods caused by heavy monsoon rains killed 12 more people in a southern Indian state and shut down one of its key airports for a third day, officials said Saturday. At least 43 people have died _ including the 12 new deaths in the past 24 hours _ this week in Andhra Pradesh state, where this year's monsoon deluge has submerged hundreds of villages and forced tens of thousands of people out of their homes, said Chief Minister Y. Rajasekhara Reddy. The casualties in Andhra Pradesh brought the nationwide death toll from this year's monsoon rains to 354, according to reports from local officials in various parts of the country, the Associated Press reported.
