Canada continues to grapple with the fallout of the ongoing conflict in Iran after the United States and Israel launched a major attack on the Middle Eastern country that left the Supreme Leader Ayatollah Ali Khamenei dead.

Prime Minister Mark Carney says Canada supports the U.S. action in Iran, but Canada will not get directly involved in the conflict.

On home soil, the Canadian Association of Chiefs of Police says there is “no indication of any imminent threat to Canada or Canadians” based on current intelligence, but police leaders are warning the public to be vigilant as airstrikes in Iran continue for a second day.

“Experience shows that periods of geopolitical tension can sometimes inspire extremist networks, hate-motivated individuals or proxy-related threat actors to exploit these situations to incite hate-fuelled violence,” the association says. “While there is no specific threat at this time, awareness and early reporting are essential components of prevention.”

Iran has retaliated to the U.S.-Israel airstrikes with missiles and drone attacks on Israel and nearby Arab Gulf countries hosting U.S. forces.

Hundreds of thousands of stranded travelers have been left scrambling as the conflict spills over, shutting down much of the Middle East to air travel.

Air Canada has cancelled flights from Canada to Tel Aviv until March 8 and halted air travel to Dubai until Tuesday.

“If you are in either of these regions, please do not head to the airport,” the airline warns.

Canada’s largest flight hub, Toronto’s Pearson Airport, is warning of delays and cancellations due to widespread airspace closures and are advising passengers to check their flight status before coming to the airport.

The conflict has shut down airports and international airspace above Israel, Qatar, Syria, Iran, Iraq, Kuwait, Bahrain, Oman and the United Arab Emirates.

Officials at Dubai International Airport — the largest in the United Arab Emirates and one of the busiest in the world — said four people were injured, while Zayed International Airport in Abu Dhabi said that one person was killed and seven others were injured in a drone strike. Strikes were also reported at Kuwait International Airport.

More than 1,800 flights were cancelled Sunday, including those in Saudi Arabia, Jordan, Turkey and Egypt, and flight cancellations are expected to continue in the coming days.

Canada is warning people to avoid all travel to large swaths of the Middle East since the conflict began yesterday, including Lebanon, Israel and Palestine, Iraq, Qatar, Bahrain, United Arab Emirates, Kuwait, Iran, Syria and Yemen.
