The United States launched attacks on Iran for the 11th consecutive night late Tuesday, as Tehran warned the United States not to attack its nuclear facilities.

The US Central Command (Centcom) said the wave of attacks was “designed to continue to degrade Iran’s ability to threaten commercial shipping” in the Strait of Hormuz.

Iranian state media reported that air defenses were activated in the capital, Tehran. Explosions were also reported in the northwestern city of Tabriz, the southeastern ports of Chabahar and Konarak, and in the southern city of Bushehr, home to Iran’s only nuclear power plant.

Iran, which has retaliated against the United States and its Middle East allies, warned of retaliation after Donald Trump said the United States would soon attack an underground nuclear site near Natanz.

Iran and the United States agreed to a ceasefire in April, but hostilities resumed last week as both countries fought for control of the vital Strait of Hormuz.

Centcom said US forces had attacked Iranian military operations centers, maritime capabilities, aircraft hangars, drone storage facilities and military logistics infrastructure.

He also accused Iran of attacking “more than 30 commercial vessels” passing through the Strait of Hormuz over the past three months.

“Unjustified attacks have endangered hundreds of innocent sailors and undermined freedom of navigation,” he said, adding that the waterway remains “open to the transit of commercial vessels.”

Kuwait’s military said early Wednesday morning that its air defenses were fighting off drone attacks from Iran, while Bahrain and Jordan said they had also intercepted drone and missile attacks.

The price of oil has risen in response to the latest rally, reaching $94 on Wednesday.

US Secretary of State Marco Rubio has said Washington is still willing to engage in diplomatic relations with Tehran, but added that he did not believe Iran was serious about talks.
