March–May 2025 United States Attacks In Yemen

In March 2025, the United States launched a large campaign of air and naval strikes against Houthi targets in Yemen. Codenamed Operation Rough Rider, it has been the largest U.S. military operation in the Middle East of President Donald Trump's second term. The strikes began on March 15, targeting radar systems, air defenses, and ballistic and drone launch sites used by the Houthis to attack commercial ships and naval vessels in the Red Sea and Gulf of Aden. On 30 April 2025, the United Kingdom joined the United States in conducting strikes on Houthi targets.

The Houthi group began targeting international shipping in October 2023, after Israel invaded the Gaza Strip in response to the October 7 Hamas attacks. Claiming solidarity with Palestinians and aiming to pressure Israel into agreeing to a ceasefire and lifting its blockade of Gaza, the Houthis launched missiles and drones at vessels traveling near Yemen, and also fired ballistic missiles at Israeli cities, killing at least one civilian in Tel Aviv. In response, the United States, the United Kingdom, and a multinational coalition began Operation Prosperity Guardian, combining naval escorts with episodic airstrikes on Houthi military and civilian infrastructure.

By mid-March 2025, the Houthis had attacked more than 190 ships, sinking two, seizing another, and killing at least four seafarers. On March 18, Trump warned Iran—longtime backers of the Houthis—that further attacks would be considered acts of aggression, despite no direct involvement.

On May 6, President Donald Trump declared the strikes to be over, "effective immediately," as a result of a ceasefire between the U.S. and the Houthis, brokered by Oman. The Houthis asserted that the ceasefire did not in "any way, shape, or form" include attacking Israel, which had just begun bombing Yemen.

Background

The Houthis are a Shia Islamist military and political group located in Yemen, backed by Iran, and widely considered part of the Iranian-led Axis of Resistance. Emerging in the 1990s, they played a major role in Yemen's civil war, opposing the Presidential Leadership Council (SLC). The group took control over northern Yemen, including the capital, Sanaa, since 2014,

The Saudi-led coalition, backed by the United States, has fought against the Houthi Movement for over a decade. Since the 7 October Hamas-led attack on Israel in October 2023, they have continued to target commercial shipping in the Red Sea using missiles, drones, and explosive-laden boats, forcing many shipping companies to reroute vessels around southern Africa at higher costs, in an attempt to force a ceasefire in the Gaza War and an end to the Israeli blockade of the Gaza Strip. Since November 2023, they have conducted over 190 attacks on shipping, sunk two vessels, seized another, and killed at least four seafarers, disrupting global trade. ''The Economist'' based in the UK reported that Red Sea cargo shipments had decreased by 70% in volume as a result of these strikes. It alleged that the Houthis had turned their strikes into a business model by requesting Protection racket payments from shipowners in exchange for safe passage, generating substantial revenue through blackmarket transactions and a form of maritime extortion.

The Houthis also conducted ballistic missile and drone attacks on Israeli cities, including Eilat and Tel Aviv, where a drone strike killed one Israeli. In response, the United States, the United Kingdom, and Israel, with support from a multi­national coalition, launched attacks in Yemen to disrupt their capabilities.

While other members of Iran's Axis of Resistance—including Hamas, Hezbollah, and Syria—suffered major setbacks, the Houthis have used Yemen's geography to continue to fight against the Presidential Leadership Council. Following a cease­fire in Gaza-Israel in January 2025, they halted their attacks, but tensions resurfaced when they warned to resume strikes on targets in Israel if Israel disrupted humanitarian aid to Gaza again, which it blocked on 2 March. Following the aid block, the Houthis set a four-day deadline for border crossings to be reopened and aid to be allowed. The Houthis announced a resumption in attacks on 11 March after the demands were not met. The Houthis also fired a missile at a US Air Force F-16 and shot down a US MQ-9 Reaper drone. President Trump redesignated the Houthis as a foreign terrorist organization in January 2025.

In February 2025, CBS News reported that President Donald Trump and Defense Secretary Pete Hegseth had rolled back constraints on American commanders, allowing them to authorize airstrikes and special operations raids outside conventional battlefields. This broadened the range of people who could be targeted, with the Houthis being among the first under the new rule.

Weapons analysts have suggested that the Houthis may have acquired advanced drone technology, potentially increasing their operational range. Many of the militia's weapons are either manufactured in underground facilities or smuggled from Iran, their primary backer. Iran's enrichment of uranium to near weapons-grade levels remains a major international concern. Meanwhile, economic hardship in Iran has fueled domestic unrest.

Prelude

Following Trump's election, Gen. Michael Kurilla, commander of the United States Central Command, proposed an 8–10 month bombing campaign based on Israel's operation against Hezbollah, where the US would strike Houthi air defenses before conducting targeted assassinations against senior Houthi officials. Saudi officials who supported Kurilla's proposal provided a list of 12 prominent Houthi leaders, stating that their assassinations would "cripple" the group. In early March, Trump partially approved Kurilla's plan, giving it 30 days to exhibit results in a campaign named "Operation Rough Rider" by Pete Hegseth.

On 13 March 2025, National Security Adviser Michael Waltz created a Signal group chat called "Houthi PC small group", for Trump administration officials to coordinate the attacks. The group included accounts that seemed to correspond to Marco Rubio, JD Vance, Tulsi Gabbard, Scott Bessent, Pete Hegseth, John Ratcliffe, Steve Witkoff, Susie Wiles, Joe Kent, and Stephen Miller. Waltz also accidentally added the editor-in-chief of ''The Atlantic'', Jeffrey Goldberg. This incident became known as Signalgate.

On the morning of 14 March, Vance messaged the group asking for the attacks to be delayed by one month, saying: "I am not sure the president is aware how inconsistent this is with his message on Europe right now" and that the attacks "risk that we see a moderate to severe spike in oil prices". But Hegseth convinced Vance to continue with the attack, saying that the attacks were "not about the Houthis. I see it as two things: 1) Restoring Freedom of Navigation, a core national interest; and 2) Reestablish deterrence, which Biden cratered." Miller messaged at 9:35 a.m. ET that Trump had given approval for the attacks.

Trump authorized the attack plan, which had been in development for several weeks, with the final order issued on Saturday, 15 March. Some members of Congress received briefings from the White House the same day. At 11:44 a.m. ET, Hegseth messaged the group operational details of the attacks, including information about targets, weapons used, and attack sequencing.
