March 28 (Reuters) - Thousands of rallies are expected across the United States on Saturday in the latest "No Kings" protest against the policies of President Donald Trump and his administration.

Organizers say that more than 3,200 events are planned in all 50 states for what they hope will be the largest single-day nonviolent protest in U.S. history. The two previous No Kings events attracted millions of participants.

March 28 (Reuters) - The Israeli military killed three Palestinian men in Gaza on Saturday in two separate air strikes, local health officials and medics said, the latest round of deadly violence despite a U.S.-brokered ceasefire that is now more than five months old.

Palestinian health officials said one man was killed in an air strike on a car in the Khan Younis area in southern Gaza, while medics said two adult brothers were killed in Shujiaya, a neighbourhood east of Gaza City.

SPLIT, Croatia, March 28 (Reuters) - The U.S. aircraft carrier Gerald R. Ford, which had been deployed in U.S.-Israeli operations against Iran, anchored in Croatia's Adriatic port of Split on Saturday for repairs and maintenance.

TheFord,America's newest and the world's largest carrier, wasoperating in the Red Sea in support of Operation Epic Fury when a non-combat fire broke out in its main laundry room on March 12, injuring three sailors.

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.
