All international trains crossing Hungary were delayed on Wednesday because of a bomb threat, Hungarian State Railway company MAV said.

A total of 18 international trains that were already in Hungary at time of the bomb threat were stopped and controlled by police before resuming service. Newly arriving trains will be controlled at the borders, MAV said in a statement.

The delays can reach from 1.5 to two hours, according to the Hungarian company.

Controls by Hungarian police are to go on until Wednesday at midnight local time.

Hungarian authorities have launched an investigation to find the person who committed the bomb threat.

MAV said about 20,000 people were affected by the delays.
