UPDATE 1-WTO building in Geneva briefly evacuated on bomb scare

(Updates with details and lifting of alert)

GENEVA, March 12 (Reuters) - The Geneva headquarters of the World Trade Organization (WTO) was partially evacuated after a bomb scare on Tuesday, but reopened for business again after police with a sniffer dog gave the all-clear.

"There was a guy who acted strangely and who parked his car suspiciously, a guy whose behaviour was notably odd," WTO spokesman Keith Rockwell told Reuters.

He said the WTO's new building had been evacuated on advice from Swiss police.

Many of the trade officials and other visitors to the lakeside headquarters were unaware of the incident, which lasted about 30 minutes. (Reporting by Tom Miles; Writing by Emma Thomasson and Emma Farge; Editing by Kevin Liffey)
