U.S. strikes on Iran's nuclear sites could heighten the threat to American operators in the region, an organisation that monitors flight risks warned on Sunday, as some airlines cancelled flights to and from Dubai and Doha.

Airlines are continuing to reroute flights away from significant swathes of Middle Eastern airspace, following recent US strikes on Iranian nuclear sites and ongoing missile exchanges in the region. The persistent avoidance of these key flight corridors was evident on Sunday, according to data from the flight tracking website FlightRadar24.
