A few days after the Trump administration announced a new, get-tough approach to Iran, one of that country's top military commanders and the armed Shiite militias he supports played a key role in the seizure of an important Iraqi city from the U.S.-backed Kurds, according to Iraqi, Kurdish and American officials.

Former U.S. national security officials told NBC News the Iranian-brokered seizure of oil-rich Kirkuk by the Iraqi government and its militia partners, which heightens the risk of civil war, amounts to an embarrassing strategic blow to the U.S. at the hands of Iran.

"It is a catastrophic defeat for the United States and a fantastic victory for Iran's Revolutionary Guard, proving that Qassem Soleimani gets his way once again," said Ali Khedery, a former senior adviser on Iraq policy in the Bush and Obama administrations.

Soleimani is head of the Iranian military's special forces and extraterritorial operations. The major general commands an elite unit known as the Quds Force and has been dubbed the most powerful intelligence operative in the Middle East. According to Kurdish and Iraqi officials, he traveled to Kirkuk last week to weigh in on the dispute between Baghdad and the Kurds over the strategically important city of Kirkuk.
