A heated confrontation erupted in the British Parliament on Wednesday when Iranian Ambassador Seyed Ali Mousavi clashed repeatedly with UK lawmakers during testimony on the Israel-Iran conflict, with the diplomat becoming visibly agitated when pressed on evidence of Iranian military support to proxy groups and nuclear weapons development. The exchange grew increasingly tense as MPs confronted Mousavi with intelligence showing 8,000 Iranian drones supplied to Russia and 22 assassination plots on British soil, prompting the ambassador to challenge the lawmakers' "moral authority" and demand they answer his questions in return, creating one of the most contentious parliamentary hearings in recent memory
