The US has released the identities of six crew members killed during the crash of a refueling aircraft in Iraq this week.

The Pentagon said the six members killed in the accident on Thursday were: John "Alex" Klinner, 33, of Auburn, Alabama; Ariana Savino, 31, of Covington, Washington; Ashley Pruitt, 34, of Bardstown, Kentucky; Seth Koval, 38, of Mooresville, Indiana; Curtis Angst, 30, of Wilmington, Ohio; and Tyler Simmons, 28, of Columbus, Ohio.

They died when a KC-135 aerial refuelling aircraft crashed in western Iraq, with the US officials saying that "the loss of the aircraft was not due to hostile fire or friendly fire."

While Klinner, Savino and Pruitt were members of the US Air Force, Koval, Angst and Simmons were stationed with the US Air National Guard.

Donald Trump has threatened more strikes on Iran's Kharg Island oil export hub.

He said the US strikes had "totally demolished" most of Kharg Island and warned that more could follow.

"We may hit it a few more times just for fun," he told NBC News.

The US has posted a video showing its Air Force B-52 Stratofortress taking off for a "night mission" during Operation Epic Fury.

"Strikes from U.S. forces continue to be unpredictable, dynamic, and decisive," the US Central Command said on X.

Two drones targeted an airbase in Kuwait housing US military staff, injuring Kuwaiti personnel and causing damage, the defence ministry said.

A drone attack late Saturday targeted the Baghdad airport complex, which houses a military base and a US diplomatic facility, two security sources told the news agency AFP.

The drones "targeted the military base" but were brought down just outside the complex, one source said, while a second source said a crashed drone sparked a huge fire outside.

Formula 1 and its governing body FIA said the Grand Prix races in Bahrain and Saudi Arabia will not happen in April because of safety concerns related to the Iran war.

“Due to the ongoing situation in the Middle East region, the Bahrain and Saudi Arabian Grands Prix will not take place in April,” F1 said. “While several alternatives were considered, it was ultimately decided that no substitutions will be made in April.”

F1 was due to race in Bahrain on April 12 and in the Saudi Arabian city of Jeddah on April 19.

“While this was a difficult decision to take, it is unfortunately the right one at this stage considering the current situation in the Middle East," said Stefano Domenicali, president and CEO of F1.

“The FIA will always place the safety and well being of our community and colleagues first. After careful consideration, we have taken this decision with that responsibility firmly in mind,” FIA President Mohammed Ben Sulayem said.

Explosions rang out over Bahrain's capital of Manama early on Sunday, according to two AFP journalists.

In a post on X at around 1 am, Bahrain's Ministry of Interior said the "siren has been sounded".

"Citizens and residents are urged to remain calm and head to the nearest safe place," it had said.

Bahrain has said it has intercepted 125 missiles and 203 drones since the start of Iran's attacks.

Iran has attacked Gulf countries housing American bases as the war in the Middle East entered day 16 on Sunday.
