US strikes Iran military site in fresh escalation after ceasefire warning

WASHINGTON — The Pentagon confirmed late Tuesday that U.S. warplanes conducted precision airstrikes on an Iranian Revolutionary Guard Corps (IRGC) military base near the town of Khash, in Iran’s southeastern Sistan and Baluchestan province. The strikes were launched in response to what the Pentagon called "credible intelligence" indicating imminent threats to U.S. forces and allies in the region.

The operation, codenamed "Operation Iron Resolve," targeted a command-and-control facility used by the IRGC’s Quds Force, according to a statement from U.S. Central Command. The Pentagon asserted the strikes were "measured and defensive," aimed at degrading the IRGC’s ability to conduct offensive operations. No U.S. or allied casualties were reported, but Iranian state media claimed "several" IRGC members were killed in the attack.

Iran’s Foreign Ministry summoned the Swiss ambassador—acting as a diplomatic intermediary between Tehran and Washington—on Wednesday to protest the strikes. Iranian President Ebrahim Raisi condemned the attack as "unprovoked aggression" and vowed a "decisive response." Meanwhile, regional analysts noted that this marks the second U.S. military action in Iran within a month, raising concerns of a broader escalation in the already volatile region.

The strikes come just days after the Pentagon issued a warning to Iran and its proxies, stating that any attacks on U.S. personnel or interests would be met with "all necessary measures." U.S. officials said the intelligence indicated plots involving drone swarms and ballistic missile attacks targeting American bases in Iraq and Syria, as well as Israeli and Gulf state positions.

Regional tensions have surged since October, when a deadly drone strike on a U.S. outpost in Jordan killed three American soldiers. The U.S. blamed Iran-backed militias for the attack, a charge Tehran denies. The current strikes represent the most aggressive U.S. military action inside Iran since that incident, signaling a shift from proxy confrontations to direct strikes on Iranian soil.

Analysts at the Washington-based Institute for the Study of War (ISW) described the strikes as a "calibrated escalation," designed to send a strong message to Tehran without triggering an all-out conflict. "The U.S. is walking a tightrope," said ISW senior analyst Michael Kofman. "They want to deter further attacks but avoid provoking a wider war."

The IRGC’s Quds Force, led by General Esmail Qaani, has been a primary target of U.S. sanctions and covert operations in recent years. The facility struck Tuesday, located 40 kilometers west of Khash, is believed to be a key hub for coordinating attacks by Iranian-backed militias in Iraq, Syria, and Yemen. U.S. officials said the site was chosen to minimize civilian casualties while maximizing the destruction of military infrastructure.

1. October 28, 2023 — U.S. outpost in Jordan hit by drone, 3 soldiers killed.
2. November 2023 — U.S. sanctions 12 IRGC officials in response.
3. December 15, 2023 — Pentagon warns Iran of "all necessary measures" amid rising threats.
4. January 2, 2024 — U.S. conducts strikes near Khash, Iran.

While the U.S. has conducted hundreds of airstrikes in Iraq and Syria targeting Iranian-backed militias since October, this marks the first time American forces have struck directly inside Iran. The move underscores the Biden administration’s willingness to escalate military action to protect U.S. interests and allies, despite the risks of a broader regional conflict.
