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.

World leaders at the Group of Seven summit in Canada scrambled Monday to find a way to contain the escalating conflict between Israel and Iran.

U.S. President Donald Trump on Monday night cut short his participation at the G7 summit in Alberta, Canada, by two days to focus on the conflict between Israel and Iran, the White House said.
