Bahrain is reporting the highest number of casualties in a single strike on the Gulf states since the war began.

Its Health Ministry says the drone attack injured 32 civilians, including four children, the youngest of whom is two months old

At least 10 people have been killed across the Gulf so far, most of them security personnel or foreign workers. Qatar, Kuwait, the United Arab Emirates and Saudi Arabia also reported new attacks overnight.

Riyadh said it intercepted and destroyed two waves of drones heading towards a major oilfield. An earlier drone strike hit the US embassy and the State Department has now ordered non-essential government employees to leave the country.

Officials in Iran have warned that they could broaden attacks on regional infrastructure if Israeli and US strikes on their own facilities continued.

Donald Trump is “not happy” with Iran’s appointment of Mojtaba Khamenei as its new supreme leader, according to a programme on Fox News.

Anchor Brian Kilmeade says he spoke to the president after the announcement, who told him: “I am not happy.”

Kilmeade did not provide further details of the conversation and Trump has yet to comment publicly.
