Tehran has been shrouded in thick black clouds dropping 'acid rain' on the Iranian capital since Israeli strikes hit oil storage depots and other industrial sites.

The Israeli military said it struck fuel sites in Tehran last weekend that distribute fuel "to various consumers, including military entities in Iran."

"This is a significant strike that constitutes an additional step in deepening the damage to the military infrastructure of the Iranian terrorist regime," the Israel Defense Forces (IDF) said in a statement.

Social media footage shows huge fires over the Tehran skyline.

CNN reports targets included the Tehran's biggest fuel storage facilities, the Shahran Oil Deposit.

Thick plumes of smoke have been drifting from the compound into the city centre, triggering the rare weather phenomenon of black rain.

Australian authorities are being urged to offer protection for the visiting Iranian women's football team, which is scheduled to return to their war-torn homeland.

The side were eliminated from the Women's Asian Cup tournament after losing to the Philippines on the Gold Coast yesterday.

Their team bus was met by a large group of protesters who called for them to receive protection.

Activists told 9New they saw at least one of the players make a sign for help, and urged the federal government to offer them shelter.

"If they want stay here. We must help them," one protester said.

The Iranian team's silence during the anthem before an opening loss to South Korea last Monday was viewed by some as an act of resistance and others as a show of mourning.

Amid concerns for player welfare following reported criticism in the Iranian media, the Australian Iranian Council wrote to Home Affairs Minister Tony Burke urging the government to protect the squad members while they're in Australia.

It launched an online petition, which had more than 50,000 electronic signatures before kick-off Sunday, urging Australian authorities to "ensure that no member of Iran's women's national football team is to depart Australia while credible fears for their safety remain."

British Prime Keir Starmer has spoken to US President Donald Trump overnight about the military cooperation between the two countries in the Middle East.

Trump has rebuked Starmer on several occasions since they last spoke over a week ago about the prime minister's initial decision not to permit the US military to use British bases in the initial attacks against Iran, describing him at one point as "not Winston Churchill."

Starmer has now granted permission for "defensive" actions against Iranian missile sites from UK bases after Iran started attacking countries throughout the region.

Starmer's office in No. 10 Downing Street said the pair discussed the military cooperation between the UK and US through the use of bases "in support of the collective self-defence of partners in the region."

Starmer also shared his "heartfelt condolences" following the deaths of six American soldiers.

The body tasked with choosing Iran's next supreme leader has reached a decision, several hardline members said, without naming the candidate chosen.

One senior cleric in the 88-member Assembly of Experts, Ayatollah Ahmad Alam al-Hoda, was quoted by the semi-official Mehr news agency as saying that: "The elections for the leadership have been held and the leader has been appointed."

There has been speculation Mojtaba Khamenei, the second son of the assassinated Ayatollah Ali Khamenei, will be announced supreme leader.

US President Donald Trump has flagged the idea of having a say in the selection of who takes the top job in Iran, but he country's Foreign Minister Abbas Araghchi is having none of it.

"We allow nobody to interfere in our domestic affairs. This is up to the Iranian people to elect their new leader," Araghchi NBC in the United States.

"It's only the business of the Iranian people, and nobody else's business."

But Trump told US media that the new supreme leader "is not going to last long" without his approval.

"He's going to have to get approval from us," Trump told ABC News in an interview. "If he doesn't get approval from us he's not going to last long."

A deepening fuel crisis is leaving Australian farmers running low on diesel and prompting calls for price monitoring to be expanded.

Following concerns that war in the Middle East could impact crude oil supplies and accusations Australian oil companies were profiteering, Nationals Leader David Littleproud said the fuel situation was "frightening".

"Australians should understand that while they can go to the servo and fill up, our farmers aren't getting their supplies," he said.

"If they run out, they can't produce your food and fibre. There is supply, and this is the issue. There's supply sitting there, but the big oil companies won't release it to the independents and to the small wholesalers."
