The Iran men's national team wore black armbands and posed with school rucksacks as the national anthem played before a match with Nigeria to remember the victims of a strike on a primary school in Iran on the first day of the Middle East war.

The airstrike on the school in the southern Iranian city of Minab on February 28 killed at least 170 people including students and teachers.

The attack happened on the day the United States and Israel launched the war with attacks across Iran.

The ability of Israel's highly sophisticated air defences to keep intercepting Iranian attacks is coming under scrutiny as the Middle East war drags on into a second month.

The military has dismissed reports that it is running low on the interceptors used to shoot down the steady stream of Iranian missiles and Hezbollah rockets fired at Israel.

However, some analysts suggest that the war against Iran has significantly drained allied resources, with long-range interceptors among the most severely depleted.

GRAPEVINE, Texas, March 28 (Reuters) - When former Congressman Matt Gaetz opened his speech by aligning with a Republican faction "loyal to only one nation," his message to the Conservative Political Action Conference was clear: It was a veiled swipe at perceived Israeli influence over U.S. politicians, even without naming Israel outright.

KYIV, March 28 (Reuters) - Ukraine's President Volodymyr Zelenskiy said on Saturday he had met with United Arab Emirates President Sheikh Mohammed bin Zayed Al Nahyan and that they had agreed to cooperate in the field of security and defence.

"Our teams will finalise the details," Zelenskiy said on the Telegram app.

The two leaders tackled opportunities to advance bilateral cooperation under the Comprehensive Economic Agreement between the two sides, the Emirati state news agency WAM said, without further elaborating.

The Israeli military said it had struck an Iranian research facility for naval weapons, while a series of loud explosions rattled Tehran as night fell on Saturday.

The fresh attacks on the capital came after Yemen's Houthi rebels announced their entry into the Middle East war by launching a missile towards Israel.

The intervention of Iran's Yemeni allies is sure to spark concern about disruptions to Red Sea shipping, which would only compound the widening economic fallout from the effective closure of the vital Strait of Hormuz off Iran.

ISLAMABAD/ ISTANBUL, March 28 (Reuters) - Pakistan will host Saudi Arabia, Turkey and Egypt for talks from Sunday on the Iran war as Islamabad positions itself as a potential venue for U.S.-Iran negotiations on the month-old conflict.

The four countries' foreign ministers will hold "in-depth discussions on a range of issues, including efforts to de-escalate tensions in the region" during the two-day talks, Pakistan's foreign ministry said in a statement on Saturday.

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".
