Biden vows US 'shall respond' after troops killed in Jordan

Iran-backed militants launch a drone attack on a base in Jordan, killing three American troops and injuring over 30. President Joe Biden blames Iran-supported groups and vows a calculated response. The attack escalates tensions in the Middle East and raises concerns of a potential conflict involving Tehran. Hamas spokesperson Sami Abu Zuhri interpreted the attack as a warning to the US, indicating potential wider conflict if the aggression in Gaza persists.
