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.” Iran said Sunday that it struck an unmanned US military boat in the Strait of Hormuz. US Central Command, which oversees the US military operations in the Middle East, did not confirm the claim or respond to request for comment. It comes one day after the US said it struck Iranian oil tankers in retaliation for Iran launching ballistic missiles at Navy warships.
