President Fidel Castro on Monday lamented that the U.S. government had not still responded two weeks after he offered to send nearly 1,600 Cuban doctors to help Hurricane Katrina victims, saying the team could have saved lives. The U.S. government has suggested there were sufficient American physicians to care for the ailing among those displaced by the storm across Louisiana and Mississippi. An appeal for help from the U.S. Department of Health and Human Services "has seen a robust response from the American medical community," State Department spokesman Sean McCormack said earlier this month.
