Middle East Conflict Escalates as Iran Warns of 'Faster, Heavier' Retaliation

The conflict in the Middle East continues to escalate as Iran's chief negotiator warns that its retaliation will be 'faster, heavier and more painful'.

Iran claims to have struck an unmanned American military vessel in the Strait of Hormuz, but the US military denies this, calling it a 'total lie.'

The US had previously accused Iran of launching ballistic missiles at Navy warships, prompting a retaliatory strike on Iranian oil tankers.
