Hungary ? A Slovak military plane carrying troops back from Kosovo crashed into a mountainside in northeastern Hungary, killing at least 42 people, officials said today.

Only one person survived after the AN-24 aircraft went down near the Slovak border, said National Police spokesman Laszlo Garamvolgyi.

A NATO officer, who spoke on condition of anonymity because he was not authorized to speak on to the media, said in Kosovo that the soldiers were returning home after serving in the NATO-led peacekeeping force. Officials say Slovak troops help patrol the boundary between Kosovo and Serbia.
