Brazil flooding death toll rises to 90 as more than 155,000 people displaced

At least 361 injured and 131 missing in southern part of country from what governor called his state's biggest climate catastrophe'

The death toll from what authorities call the worst climate disaster ever to strike southern Brazil has risen to 90, after ferocious rain flooded huge stretches of Rio Grande do Sul state, displacing more than 155,000 people and forcing the closure of the main airport in the country's fifth biggest city.

Photographs of the Porto Alegre airport, one of Brazil's busiest, showed its main terminal had been completely inundated and a cargo plane parked in an expanse of water next to a pair of semi-submerged boarding stairs.
