U.S. finds itself drawn into a remote conflict with Iran after the death of three of its soldiers in a drone attack on the Jordanian-Syrian border this Sunday.

Pressure is mounting on President Joe Biden who has promised “substantial” retaliation. These are the first American soldiers killed in the Middle East since the start of the war between Israel and Hamas on October 7. For its part, Tehran has denied any involvement in Sunday's attack, and warns of a regional escalation.
