Leaders of some of the world’s biggest economic powers will arrive in the Canadian Rockies on Sunday for a Group of Seven summit overshadowed by a widening war across the Middle East and U.S. President Donald Trump’s unresolved trade war with allies and rivals alike.

At previous moments of tension over decades of rivalry with Western foes, Iran was able to project power across the Middle East using a network of close allies that meant any strikes against it threatened to trigger a formidable response.

Russian President Vladimir Putin and U.S. President Donald Trump held a 50-minute phone call Saturday to discuss the escalating situation in the Middle East and Ukraine peace talks, Putin aide Yuri Ushakov said.

The US State and Defense departments on Wednesday made efforts to arrange the departure of non-essential personnel from locations around the Middle East, according to US officials and sources familiar with the efforts.

Israel’s attack on Iran has catapulted their long-running conflict into what could become a wider, more dangerous regional war and potentially drive prices higher for both businesses and households.

The Russian leader briefed Trump on his recent talks with officials in Iran and Israel, and reiterated Moscow's proposal to seek mutual solutions on the Iranian nuclear issue.

Traders on Friday exchanged the most $80 West Texas Intermediate (WTI) crude oil call options since January, expecting more upside to prices after Israeli airstrikes on Iran sparked fears of a wider Middle East conflict.

Global air traffic has been disrupted following Israel’s strikes on Iran Friday, with several major airlines suspending flights to and from locations in the Middle East and rerouting their planes to avoid much of the region’s airspace.
