Airlines have cancelled or rerouted flights to and from the Middle East, as the conflict between Israel and Iran raged, BBC reported.

Qatar's Doha airport, a critical hub in the region, halted operations on Monday, after Iran fired missiles at a US military base in the country, in what it said was retaliation for American strikes against its nuclear sites over the weekend.

Flights were temporarily paused at Dubai airport in the United Arab Emirates (UAE), the world's busiest air terminal, as passengers were told to expect further delays and cancellations.

More than a dozen airlines have cancelled flights to parts of the region after tension mounted in recent days, according to BBC.
