WASHINGTON, April 27 (Reuters) - A U.S. official said on Monday that President Donald Trump is unhappy with an Iranian proposal because it did not address Iran's nuclear program.

"He doesn't love the proposal," the U.S. official said, referring to Trump.

Earlier in the day, Trump discussed the proposal with his top national security aides. The U.S.-Iran conflict remains in a stalemate with energy supplies from the region reduced.

April 27 (Reuters) - Afghanistan is at risk of losing more than 25,000 female teachers and health workers by 2030 if the Taliban-led country's restrictions on girls' education and women's employment are not lifted, according to a new UNICEF report released on Monday.

The Taliban has banned women from most public sector jobs and limited girls to receiving an education only until the age of 12.

April 27 (Reuters) - The United States and Iran clashed at the United Nations on Monday over Tehran's nuclear program and its selection to be one of dozens of vice presidents at a month-long conference to review the nuclear Non-Proliferation Treaty.

April 27 (Reuters) - Iraq's alliance of Shi'ite political blocs, the Coordination Framework, on Monday named Ali al-Zaidi as its nominee for the post of prime minister, said a coalition statement.

VALLETTA, April 27 (Reuters) - Malta will hold a parliamentary election on May 30, Prime Minister Robert Abela said on Monday, calling the vote a year before his current five-year term expires.

Abela said in a televised message that with the coming months expected to be "crucial" given the international situation, Malta needed a government which could focus solely on stability.

WASHINGTON, April 27 (Reuters) - U.S. President Donald Trump discussed a new Iranian proposal on resolving the war with Tehran with his top national security aides on Monday, White House press secretary Karoline Leavitt told reporters.

Answering questions at a briefing, Leavitt did not offer an opinion of the proposal, in which the Strait of Hormuz would be opened and Iran's nuclear program discussed at a later date. But she said Trump's bottom line demands remain the same.

France said Monday that Iran must be ready to make "major concessions" to end a crisis, as countries piled pressure on Tehran at a UN session on its control of the key Strait of Hormuz.

"There can be no lasting solution to this crisis unless the Iranian regime agrees to major concessions and a radical shift in its stance," Foreign Minister Jean-Noel Barrot told the UN Security Council.

The head of the UN's maritime agency said Monday there was "no legal basis" for imposing any fees for ships to pass through the Strait of Hormuz.

Shipping through the narrow strait has been strangled since the US and Israel attacked Iran in late February.

Iran has sealed off the passage, sharply cutting oil and gas flows and sending prices soaring, while the US has blockaded Iranian ports. Tehran has also said it wants to impose transit fees as part of any lasting peace deal.

Signatories of the landmark nuclear non-proliferation treaty began a meeting Monday at the United Nations as fears of a renewed arms race escalate, with atomic powers again at loggerheads over safeguards.

In 2022, during the last review of the treaty considered the cornerstone of non-proliferation, UN Secretary-General Antonio Guterres warned humanity was "one misunderstanding, one miscalculation away from nuclear annihilation."

On Monday he warned "the drivers" of nuclear weapons proliferation were accelerating.
