At least 12 people were killed in an accident involving a Polish bus in northern Croatia on Saturday. The accident happened near Breznicki Hum, 60 kilometers from the capital Zagreb. 43 others were injured, 18 of whom are in critical condition.

    According to the Croatian Ministry of the Interior, all victims have Polish nationality.

    The vehicle was on its way to Zagreb. The passengers were pilgrims en route to Medjugorje, a Roman Catholic temple in southern Bosnia and Herzegovina.

    The bus drifted off course and ended up in a gutter next to the road, according to the ministry. Rescue workers from the police and fire brigade and medical personnel are on the scene to help the occupants.
