Kiev's main airport has been hit by a "spam attack" that could cause some flights to be delayed, the operator, Boryspil, said.

"In connection with the irregular situation, some flight delays are possible," Director Yevhen Dykhne said in a post on Facebook.

Earlier, the central bank said a number of Ukrainian commercial banks and state and private firms had been hit by cyber attacks via an "unknown virus".
