EVIAN-LES-BAINS, France/DUBAI: Leaders of the G7 countries demanded a ceasefire in Lebanon on Wednesday and said they will ​diversify energy supply routes to reduce dependence on the Strait of Hormuz in response to the war in Iran, as they welcomed an interim deal to end the conflict.

The leaders met for a summit in the French town of Evian-les-Bains on Lake Geneva, while details of the US-Iran ceasefire agreement trickled out of Washington and Tehran ahead of its formal unveiling, expected on Friday across the nearby Swiss border.

The US-Iran agreement is expected to launch negotiations toward a final settlement to end the war, which has killed more than 7,000 people, mostly in Iran and Lebanon.

“We underline the need for the negotiation … to address the threats posed by Iran in the region and beyond and ensure that they never obtain a nuclear weapon,” the leaders said in a statement.

The summit gave US President Donald Trump a chance to present his deal with Iran to major allies Britain, Canada, France, Germany, Italy and Japan.
