Canada's Prime Minister Mark Carney on Wednesday said a US-Iran deal to end the Middle East war could be a "game changer" in the region and beyond.
There is "a likelihood that this memorandum of understanding agreement could be a game changer", Carney told reporters on the third day of a G7 leaders' meeting in the French town of Evian.
He pointed to encouraging discussions, which included US President Donald Trump, on Ukraine and Lebanon at the summit.
