US Secretary of Transportation: A communication problem is the reason for the suspension of all flights in the US.
We previously reported that the US Federal Aviation Administration suspended all flights in this country due to "exceptional conditions and Yemeni reasons".
The US Secretary of Transportation, Sean Duffy, said that all airports in the US are grounded after a communication problem that affected all air traffic control centers.
He said FAA technicians are investigating the problem and will provide immediate updates as soon as information is received.
