Bombing intensified in the Middle East for the seventh consecutive night, with Iran threatening a “full-scale offensive” in response to American strikes and hitting several US military sites in Kuwait, Jordan and Bahrain.

Iran’s Revolutionary Guards said on Saturday that two oil tankers directed by “deceptive American intelligence agencies” exploded after hitting mines in the Strait of Hormuz, which the US military quickly denied.

The Revolutionary Guards also said on state television they “stopped” four ships trying to transit the critical waterway.

Major General Mohsen Rezaei, a senior military adviser to Iran’s supreme leader, said Tehran will resume “full-scale offensive operations” if US strikes against it continue for another two or three days.

“Iran will no longer limit itself to retaliatory, like-for-like responses… and no political border will be safe,” Rezaei said, according to the Iranian news agency IRIB.
