Iran's top negotiator threatens 'faster, more intense' response to US attacks

Iran's top negotiator Mohammad Bagher Ghalibaf threatened on Sunday to launch swifter and more forceful responses to US attacks, after Tehran targeted American warships in retaliation for US attacks on tankers.

"The Americans must have understood that the era of proportionate responses has come to an end," said Ghalibaf in a speech carried by state media, adding that "any aggression against Iran's interests and security will receive a faster, more intense and more painful response".
