We'll be back tomorrow morning with a new blog bringing you the latest developments in the Middle East war.

Here’s a recap of today’s key developments:

• German Foreign Minister Johann Wadephul accused Russia of helping Iran identify potential strike targets at G7 meeting in France.

• Iran's Islamic Revolutionary Guard Corps has warned civilians to leave areas near US forces across the Middle East.
• Donald Trump has singled out Australia while accusing allies of failing to help the US secure the Strait of Hormuz.
• Prime Minister Anthony Albanese said he wouldn't comment on the remarks, but made the point Australia wasn't consulted on America and Israel's decision to start attacking Iran.
• The US president has also extended his deadline for Iran to open the Strait of Hormuz to April 6, saying he will hold off on bombing Iran's energy plants and that talks are going "very well".
• G7 talks underway in attempt to narrow differences between the US and its allies.
• Trump weighs sending another 10,000 ground troops to the Middle East, reports say.
• The IRGC said it attacked Israeli and US forces yesterday, while Israel said it carried out "wide-scale" strikes on Tehran today.
• A trickle of ships has been let through the Strait of Hormuz. Trump says Iran has allowed 10 ships to pass as a "present".

Ukraine and Saudi Arabia have signed a defence agreement which lays the groundwork for future investments, contracts and technological cooperation.

Ukrainian President Volodymyr Zelenskyy who is visiting Saudi Arabia, said the agreement was signed ahead of a meeting with Saudi Crown Prince Mohammed bin Salman.

"We are ready to share our expertise and systems with Saudi Arabia and to work together to strengthen the protection of lives," Zelenskiy said on the Telegram app.

Ukraine has emerged as a vital source of expertise in anti-drone warfare in the Middle Eastern conflict and has sent advisors to several Gulf countries.

The UNHCR has warned Lebanon's humanitarian crisis is teetering on the brink of catastrophe. 

"The situation remains extremely worrying and the risk of a humanitarian catastrophe... is real," Karolina Lindholm Billing, the agency's representative in Lebanon, said.

The UNHCR said since March 2 more than a million people, one in five residents, have been forced to flee their homes and UNICEF estimates more than 370,000 children have been displaced. 

The Saudi Arabian Ministry of Defence announced they intercepted and destroyed three drones in the Riyadh region on X. 

A spokesperson for the ministry said debris from the interception fell in the vicinity of a military site without causing any injuries. 

The Ministry announced minutes later another drone had been intercepted and destroyed in the Riyadh region. 

Polish Prime Minister Donald Tusk has warned of "a new escalation" in the US-Israel war against Iran. 

"I have reasons to believe, also based on information we've received from our allies, that stabilisation is unlikely in the coming days. On the contrary, a new escalation may occur," Mr Tusk said.

Chinese foreign minister Wang Yi said initiating peace talks in the Iran war would be "no easy task" but it would be "conducive to restoring normal navigation through the Strait of Hormuz," in a call with  Pakistani counterpart Ishaq Dar. 

The two "agreed to jointly promote a ceasefire and cessation of hostilities and the resumption of peace talks, to ensure the safety of non-military targets and waterways," according to a summary of the call released by the Chinese ministry.

Mr Yi expressed support for Pakistan taking on the role of mediator.

German Foreign Minister Johann Wadephul has accused Russia of helping Iran identify potential strike targets, at a G7 meeting in France. 

Mr Wadephul said President Vladimir Putin was hoping to use the conflict as a distraction from the ongoing war in Ukraine. 

"Putin cynically hopes that the escalation in the Middle East will divert our attention from his crimes in Ukraine," Mr Wadephul said.

 "This calculation must not succeed. We see very clearly how closely the two conflicts are intertwined. Russia is evidently supporting Iran with information about potential targets."

Mr Wadephul also said he told US Secretary of State Marco Rubio Germany was willing to help play a role in the Strait of Hormuz after hostilities end.

We previously reported UK Foreign Secretary Yvette Cooper was "deeply concerned" over the growing links between Iran and Russia.

Maria Martinez of the IFRC said the Iranian Red Crescent continues to serve as the only nationwide humanitarian organisation operating across the country amidst the escalating conflict.
