An object was then found near the south runway and a bomb disposal robot was sent to the site, police said. Berlin: Flights to an airport in eastern Germany had to be diverted overnight after a "security-related incident" involving at least one unidentified object, police said Wednesday. A passenger plane from Mallorca as well as several cargo planes destined for Leipzig-Halle airport had to be sent to other locations after a flying object was spotted near the airport around 11:40 pm (2140 GMT) on Tuesday. An object was then found near the south runway and a bomb disposal robot was sent to the site, police said. Last year, a Chinese national was convicted of passing on information about flight schedules and cargo movements at Leipzig-Halle airport to a man spying for Beijing.
