A carrier that has been battling to regain flyers' confidence after a fatal crash last year says it has suspended its flights.

Dana Air spokesman Tony Usidanem said Sunday that Nigeria's aviation ministry asked for the suspension in a letter received Saturday. He said the letter did not state a reason why.

Usidanem said a meeting with the ministry Monday would bring more clarity.

The ministry spokesman could not immediately be reached for comment.

A Dana Air crash on June 3 left more than 160 people dead, leading the carrier to lose its license. It resumed its operations two months ago.

The suspension comes days after another major airline halted its operations over a strike.
