Group of Seven leaders arrived in Kananaskis, Alberta, Canada, on Sunday for three days of intense discussion amid increased tension in the Middle East and President Donald Trump’s reshaping of global alliances.

The summit comes amid rising international tensions, as Trump and other allies continue their quest for an accord between Russia and Ukraine.

U.S. President Donald Trump said on Monday he will soon be back in Washington from the Group of Seven nations’ summit held in Canada due to the situation in the Middle East where the conflict between Iran and Israel has escalated.
