'Bomb threat' causes delays at Zurich airport

Zurich airport was partially closed on Monday evening after receiving an unspecified threat, a spokeswoman said.

Geneva: A bomb threat caused flight delays and the partial shut-down of Switzerland's main airport in Zurich before security forces gave the all-clear, reports and officials said.

Around a dozen flights were delayed late on Monday by up to 30 minutes, police said, as a result of what they said was an unspecified threat. No flights were cancelled.

Local media said the security alert had been caused by an anonymous caller making a bomb threat.

"Everything is back in order and flights will resume as normal" on today, said Carmen Surber, spokeswoman for the local police.
