(QHA) -

Ukraine’s state aviation service has suspended flights to and from three major airports - Kharkov, Dnepropetrovsk and Zaporozhye - for security reasons, a local daily has said with reference to the service’s chief, Denis Antonyuk.

The measure is effective starting from [midnight] on Saturday, December 13.

Antonyuk said “security considerations” were the reason. He did not elaborate.

This is not the first time the Ukrainian state aviation service closes Ukrainian airports to flights. Air links with Donetsk have been disrupted since May. Flights between Kharkov and Moscow were banned last May, too, and between Dnepropetrovsk and Moscow, in December.
