NEW DELHI - Some commercial airlines on Wednesday rerouted flights crossing the Middle East to avoid possible danger amid escalating tensions between the United States and Iran.

Australian carrier Qantas said it was altering its London to Perth, Australia, routes to avoid Iran and Iraq airspace until further notice. The longer route meant that Qantas would have to carry fewer passengers and more fuel to remain in the air for an extra 40 to 50 minutes.

Malaysia Airlines said that "due to recent events,'' its planes would avoid Iranian airspace.

Singapore Airlines also said that its flights to Europe would be re-routed to avoid Iran.

The U.S. Federal Aviation Administration said it was barring American pilots and carriers from flying in areas of Iraqi, Iranian and some Persian Gulf airspace. The agency warned of the "potential for miscalculation or mis-identification" for civilian aircraft amid heightened tensions between the U.S. and Iran.

Such restrictions are often precautionary in nature to prevent civilian aircraft from being confused for ones engaged in armed conflict. The FAA said the restrictions were being issued due to ``heightened military activities and increased political tensions in the Middle East, which present an inadvertent risk to U.S. civil aviation operations.’'

Following the FAA, India's Directorate General of Civil Aviation advised Indian commercial carriers to avoid Iranian, Iraqi and Persian Gulf airspace.

At least two Kazakh airlines - Air Astana and SCAT - were considering rerouting or canceling their flights over Iran following the crash of a Ukrainian plane that killed 176 people.

The plane had taken off from Imam Khomeini International Airport in the Iranian capital when a fire struck one of its engines, said Qassem Biniaz, a spokesman for Iran's Road and Transportation Ministry.

Kazakhstan's officials said that Air Astana, the country's flagship carrier, "is currently holding a meeting on whether to reroute or ban'' flights. SCAT, one of the largest airlines in Kazakhstan, told Russia's Interfax news agency that they were also considering rerouting flights. The emergency flight restrictions follow Iranian ballistic missile strikes Tuesday on two Iraqi bases that house U.S. troops. Those strikes were retaliation for the U.S. killing of Iranian Revolutionary Guard Gen. Qassem Soleimani in a drone strike near Baghdad last week.
