President Donald Trump left the G7 summit in Canada a day ahead of schedule to address the escalating crisis between Israel and Iran, leaving unfinished business for the remaining world leaders.

The four-day conflict has taken a grim toll, with Iran suffering the brunt of the casualties—at least 224 people dead, including 70 women and children, and 1,277 injured, according to official figures.

What began with Israeli strikes on Iranian nuclear facilities and other targets has now spiraled into the world’s first full-scale example of what is a “threshold war”.

As soon as the first attacks happened, the Iranian airspace was deserted and commercial airlines could be spotted avoiding the entire region where missiles could fly. Even Israeli airlines said they had relocated their aircraft to safer countries away from the conflict.

The Group of Seven nations expressed support for Israel in a statement issued late on Monday and labeled its rival Iran as a source of instability in the Middle East, with the G7 leaders urging broader de-escalation of hostilities in the region.
