MILAN (AP) — A small tourist plane crashed onto high-speed train tracks Saturday while attempting to land at the small Urbe civilian airport in Rome, injuring the two people on board, the news agency ANSA reported.

An unidentified witness told Sky TG24 that the plane crashed into one set of tracks, leaving clear parallel tracks where a high-speed train passed shortly after the crash. The witness said the pilot was able to free himself, while rescue workers removed the passenger.

Both were in serious condition, ANSA said.

The cause wasn't immediately known.

The Italian State Railway said the crash didn't damage the line and that traffic would be able to resume normally once the aircraft is removed. In the meantime, traffic was being diverted to other tracks, creating delays.
