(Reuters) - Flights to Tehran were cancelled on Thursday and Friday after Canada and others said an Iranian missile brought down a Ukrainian airliner, probably by mistake. Tehran denied a missile took down the plane.
Earlier this week, flights were rerouted or cancelled to avoid airspace over Iraq and Iran following an Iranian missile strike on U.S.-led forces in Iraq.
Here is a list of measures taken by carriers so far:
Germany's Lufthansa and Austrian Airlines suspended flights to Tehran until Jan. 20.
The Lufthansa Group airlines earlier cancelled flights to Tehran on Thursday and Friday.
French airline KLM Air France suspended flights over Iraqi and Iranian airspace.

Australia's Qantas Airways Ltd adjusted routes to avoid both countries' airspace, adding up to 50 minutes to Perth-London flights and requiring it to reduce passenger numbers to carry the necessary fuel.
Transport Canada said Air Canada was altering its routes.
The United Arab Emirates General Civil Aviation Authority said:
"The General Civil Aviation Authority (GCAA) calls national air operators to evaluate flight path risks that may affect aviation operations, the GCAA continues to monitor and assess regional developments, and will take all necessary and appropriate measures promptly."
