The Canadian Government has issued an updated travel advisory warning against all non-essential travel in Iran, following the escalation of tensions between Iran and the US, and on the same day a deadly plane crash in Tehran killed 176 people. While the advisory does not specifically mention Wednesday morning's crash, it has been recently updated to acknowledge the region's "volatile security situation."\nEarly on Wednesday morning, Global Affairs Canada updated its travel advisory warnings for the country of Iran, urging all Canadians and Canadian-Iranian dual citizens to avoid non-essential travel to the region.\nThe government's advisory describes the security situation in Iran as "volatile," and suggests that there's a serious risk of "terrorism and arbitrary detention" in the country.\nThe statement explains that Canadians, particularly dual Canadian-Iranian citizens, are at risk of being "arbitrarily questioned, arrested and detained" in the region, as Iran does not officially recognize dual nationality.\nThis latest advisory update follows escalating tensions between the US and Iran, after Iran launched a ballistic missile attack on two Iraqi bases that were housing U.S. soldiers.\nA level 4 “Do Not Travel” warning remains in place for areas around the borders with Afghanistan and Iraq.\nThe Canadian Government also urges citizens to avoid all travel to areas within 10 km of the Iraq border, due to ongoing conflict within the country, as well as cross-border conflicts.\n#Iran: Avoid non-essential travel to Iran due to the volatile security situation and the regional threat of terrorism. https://t.co/YCAffTEo6W pic.twitter.com/yOeSIQTbQY— Travel.gc.ca (@TravelGoC) January 8, 2020\nLast week, the Canadian government updated their travel advisory for Iraq, following a U.S. airstrike near an airport in Baghdad that killed a top Iranian general and Iraqi military leaders.\nThe report from Global Affairs Canada explained: "This attack has led to increased tensions in the region.
