A Lufthansa passenger jet made an emergency landing in the southern Polish city of Katowice on Monday after a drunk, unruly passenger began shouting that he was a terrorist, border guards said.

The middle-aged, Russian-speaking passenger offered no resistance when an anti-terrorist squad boarded the plane to remove him, border guard spokesman Cezary Zaborski said. The passenger was due to be questioned later when he sobered up.

The Lufthansa Airbus A320 with 118 people on board continued its journey after a one-hour delay.
