At least nine people in Oman were killed and 200 injured after a tropical storm swept through the Arabian Peninsula state, causing at least $50m worth of damage, officials said on Thursday. The storm, which began on Tuesday, flooded many parts of the country, prompting 60 patients to be evacuated from two hospitals by government helicopters. "Nine died in the storm and about 200 were injured. In some parts of the country, the water level was six feet high," a rescue services spokesman said. The two hospitals had to be closed.
