Iran’s president warned that his government was poised to introduce tough new measures against the coronavirus Wednesday as the death toll from one of the world’s deadliest outbreaks topped 2,000. President Hassan Rouhani said that the new measures, which could be adopted as soon as Wednesday evening, included Iran’s first restrictions on movement to try to stem the spread of the virus and were likely to be “difficult” for the public. “There has been a long debate within the National Committee for Fighting the Coronavirus about how to strengthen the measures we have taken,” Rouhani said in televised comments to the cabinet.
