US President Donald Trump is abruptly leaving the Group of Seven summit, departing a day early on Monday as the conflict between Israel and Iran intensifies and the US leader has declared that Tehran should be evacuated 'immediately.'

World leaders had gathered in Canada with the specific goal of helping to defuse a series of global pressure points, only to be disrupted by a showdown over Iran's nuclear program that could escalate in dangerous and uncontrollable ways. Israel launched an aerial bombardment campaign against Iran four days ago.

At the summit, Trump warned that Tehran needs to curb its nuclear program before it's 'too late.' He said Iranian leaders would 'like to talk' but they had already had 60 days to reach an agreement on their nuclear ambitions and failed to do so before the Israeli aerial assault began. 'They have to make a deal,' he said. Asked what it would take for the US to get involved in the conflict militarily, Trump said Monday morning, 'I don't want to talk about that.'
