As Iran retaliates, largest US military base in Middle East hit by ballistic missile, Qatar says

Ali Larijani, the secretary of the Supreme National Security Council of Iran, said in a post to X on Sunday that Tehran is launching attacks on regional nations to target U.S. military installations there.

"To the countries of the region: We are not seeking to attack you," Larijani wrote. "But when the bases located in your country are used against us, and when the United States carries out operations in the region relying on these forces, then we will target those bases."

"These bases are not part of the land of those countries; rather, they are American soil," he added.

Since the U.S. and Israel began their strikes on Iran on Saturday, Iranian forces have launched missile and drone attacks at Kuwait, Saudi Arabia, Bahrain, the United Arab Emirates, Qatar and Oman.

The U.S. Embassy in Bahrain advised U.S. citizens in the country "that hotels might be a target for future attacks" and encouraged them to avoid hotels in the capital Manama, following a reported strike on the city’s Crowne Plaza Hotel.

The Bahrain Interior Ministry said on Sunday that the hotel was targeted resulting in material damaged but no loss of life.

The U.S. Embassy said it was "tracking confirmed reports the Crowne Plaza Hotel in Manama was struck on March 1, 2026, resulting in injuries."

Bahrain has reported being attacked with multiple waves of Iranian missiles and drones since Saturday.

Several neighbouring countries -- including Qatar, Saudi Arabia and Kuwait -- condemned a strike on the port of Duqm in Oman on Sunday.

The attack was the first apparent strike on Oman since the start of the conflict on Saturday.

Qatar called the reported attack "an unacceptable escalation and a cowardly targeting of a country playing an active role in mediation efforts."

Qatar itself reported attacks on Sunday "involving drones and cruise missiles launched by Iran." The country's Interior Ministry reported a fire in an industrial area caused by falling debris.

Elsewhere, the Kuwaiti Ministry of Defense said it "confronted a number of hostile aerial targets" on Sunday morning.

The United Arab Emirates and Bahrain also reported fresh Iranian attacks on Sunday.

A spokesperson for the Chinese Foreign Ministry on Sunday described the U.S.-Israeli killing of Iranian Supreme Leader Ali Khamenei as "a grave violation of Iran’s sovereignty and security."

"It tramples on the purposes and principles of the U.N. Charter and basic norms in international relations," the spokesperson said. "China firmly opposes and strongly condemns it."

"We urge for an immediate stop to the military operations, no further escalation of the tense situation and joint effort to maintain peace and stability in the Middle East and the world at large," the spokesperson added.
