European Council President COSTA said a united, resolute G7 is essential to helping end the Russia-Ukraine war and securing a just, lasting peace.

The US and Iran announced a preliminary agreement on Sunday to cease hostilities and reopen the Strait of Hormuz, creating a 60-day negotiation window to address Iran’s nuclear program. The memorandum has not been released and is scheduled for formal signing on June 19; text details remain unsettled and the signing process could be blocked. Major disputes persist — including the scale of economic assistance to Iran, how to handle its nuclear program, and responses to its ballistic missile program — and ongoing Israel‑Lebanon fighting could derail talks. Michael O’Hanlon, director of foreign policy at the Brookings Institution, said a temporary deal to reopen the Strait is possible but a comprehensive agreement is unlikely at present.

UK Prime Minister Starmer said the Iran agreement is very important and that he discussed it with US President Trump on Saturday.
