Here are the latest developments in the Middle East war:

- Ukraine-Qatar deal -

Qatar and Ukraine signed a defence agreement including cooperation on countering threats from missiles and drones, the Gulf state's defence ministry said, as Iran pressed an aerial campaign against its neighbours.

"The agreement includes collaboration in technological fields, development of joint investments and the exchange of expertise in countering missiles and unmanned aerial systems," the ministry said in a statement during a visit to Qatar by Ukrainian President Volodymyr Zelensky.

Qatar and Ukraine signed a defence agreement on Saturday that included cooperation on countering threats from missiles and drones, the Gulf state's government said, as Iran presses an aerial campaign against its neighbours.

Earlier on Saturday, Ukrainian President Volodymyr Zelensky -- during a previously unannounced flurry of visits to Gulf nations -- said his country and the United Arab Emirates had agreed to cooperate on defence, after Iran targeted countries in the area in retaliation for US-Israeli strikes.

An Israeli strike killed three journalists Saturday in south Lebanon, including a well-known reporter for Hezbollah's Al Manar network, with Lebanese authorities denouncing the attack as a "war crime".

The Israeli military confirmed killing Al Manar correspondent Ali Shoeib, accusing him of having "operated within the Hezbollah terrorist organisation under the guise of a journalist".

CAIRO, March 28 (Reuters) - Yemen's Iran-aligned Houthis confirmed on Saturday that they had launched an attack on Israel for the first time during the current Israeli-U.S. war against Iran, marking their entry to the conflict and raising the prospects of a broader regional confrontation.

Israel earlier said it was working to intercept a missile from Yemen.

DUBAI/WASHINGTON/PARIS, March 28 (Reuters) - Israel said it was attacking Tehran and defending against missiles fired from Iran on Saturday, after Secretary of State Marco Rubio said the U.S. expected to conclude military operations within weeks, not months.

An Iranian attack on an air base in Saudi Arabia wounded 12 U.S. military personnel, two seriously, a U.S. official told Reuters on Friday, as drones and missiles continued to strike around the Gulf.

SYDNEY, March 28 (Reuters) - Australia will amend its export-finance laws in an effort to bolster fuel security as the Iran war continues to affect the nation's ‌supply chain, Prime Minister Anthony Albanese said on Saturday.

Australia, which imports about 90% of its fuel, has experienced localised shortages in the month since the U.S. and Israel began their attacks on Iran, a widening conflict that has disrupted global fuel supply.

MIAMI, March 27 (Reuters) - Donald Trump said on Friday the United States does not "have to be there for NATO," comments that again raised questions about the U.S. president's commitment to the mutual defense provisions at the center of the transatlantic alliance.

Speaking to an investment forum in Miami on Friday night, Trump said he was upset that European NATO countries had declined to provide material support to the U.S. as it nears the fourth week of its ongoing war on Iran.

US President Donald Trump on Friday insisted Iran must open up the Strait of Hormuz to oil traffic to make a peace deal -- and dubbed the crucial waterway the "Strait of Trump."

Trump, who has renamed several buildings in Washington after himself during his second term, said his comment was a "mistake" but then added that "there's no accidents with me."

Repeating his claims that Tehran is ready to make a deal despite its denials, the 79-year-old US leader said that talks were underway to negotiate an end to the month-long conflict.

March 27 (Reuters) - Russian Foreign Minister Sergei Lavrov on Friday discussed the possibility of a diplomatic settlement in the Iran war with his Iranian counterpart Abbas Araqchi, Lavrov's ministry said.

"The ministers discussed in detail the most difficult military-political crisis in the Middle East, which erupted as a result of unprovoked American-Israeli aggression against Iran," the statement on the ministry website said.
