Abbas Araghchi says war ‘not fully come to an end’ without Israeli forces leaving territories occupied during present conflict

• Middle East crisis – live updates

Iran’s top diplomat has said a peace deal with the US would require Israel to withdraw from Lebanon, as concern grows that Israel could undermine diplomatic efforts to finally end the Middle East war, with Donald Trump even criticising his ally and war partner as irresponsible.

“Without the withdrawal of Israeli forces from the territories they occupied during this war, the war has not fully come to an end,” said the Iranian foreign minister, Abbas Araghchi.

Call at G7 summit in France comes as Ukraine president tells US counterpart Kyiv is no longer losing on battlefield

• Europe live – latest updates

European leaders at the G7 summit have urged Donald Trump to try to break the deadlock over ending the Ukraine war by taking up the proposal for him to host talks in the US between Volodymyr Zelenskyy and Vladimir Putin.

The US president lamented “the great antipathy” between the Ukrainian and Russian leaders that made it difficult to reach a settlement, and vowed to do what he could. He said Moscow “should make a deal”, noting that it had “lost a great many people, just like Ukraine”.

US president says strait of Hormuz will be open from Friday but questions remain over waterway fees and Israeli breaches of ceasefire in Lebanon

• Tallying the global cost of the US-Israel war against Iran

Donald Trump has declared that the strait of Hormuz will be “completely open” from Friday, as western leaders gathering at the G7 summit in Évian-les-Bains battled to prevent the fragile US deal with Iran from almost immediately unravelling.

“The deal’s all signed. And the strait ⁠is already partially opened,” Trump said as he arrived at the summit in France, but Israeli breaches of the ceasefire in Lebanon and Iran’s claims about its right to charge fees in the crucial waterway revealed the agreement’s many loose ends.

US president left last meeting early, but world leaders aim to end Ukraine war and push for resolution in Gaza and Iran

Emmanuel Macron, the host of the G7 summit in Évian-les-Bains, has framed an agenda to make it as palatable as possible to his guest of honour, but the French president has no idea if Donald Trump, a haphazard summit attender, will last the full three days – or disrupt the proceedings every hour he stays.

The US president quit the last G7 summit in Kananaskis, Canada, early to work on the Iran conflict, and this year, plus ça change, Iran may also draw presidential attention. For good measure, he insulted this summit’s host before leaving Canada last year, describing Macron as “publicity seeking” and adding: “Purposefully or not, Emmanuel Macron always gets it wrong.”
