THE WHITE HOUSE, Washington DC — With a ceasefire between Israel and Iran now in place, United States president Donald Trump has asked both sides in the conflict not to violate it, raising hopes of an end to the 12-day war even as deadly missile strikes have been reported in both countries.

Israeli Prime Minister Benjamin Netanyahu disclosed that his country had agreed to Trump's ceasefire proposal as it declared that Israel had already achieved its goal of removing Iran's nuclear and ballistic missile threat but also warned that it would respond forcefully to any violations to the fasttracked ceasefire agreement.

Netanyahu made the disclosure after after Iran had launched a fresh wave of missiles, killing four people, according to Israel's ambulance service, and as Iranian authorities reported nine people killed in an attack in northern Iran on Tuesday morning.

When Trump announced on Monday what he called a complete ceasefire to end the war, he appeared to suggest that Israel and Iran would have time to complete missions that were underway at which point the ceasefire would begin in a staged process.

A senior White House official said Trump had brokered the ceasefire deal in a call with Netanyahu and Israel agreeing to the proposal as long as Iran did not launch further attacks on Israel.

"On the assumption that everything works as it should, which it will, I would like to congratulate both Countries, Israel and Iran, on having the Stamina, Courage, and Intelligence to end, what should be called, 'THE 12 DAY WAR'," Trump posted on his Truth Social site.

An Iranian official earlier confirmed that Tehran had agreed to a ceasefire, but the country's foreign minister said there would be no cessation of hostilities unless Israel stopped its attacks.
