An unidentified flying object disrupted air traffic over Hangzhou, capital of east China's Zhejiang Province, late Wednesday, the municipal government said Thursday.

Xiaoshan Airport was closed after the UFO was detected at around 9 p.m. and some flights were rerouted to airports in Ningbo and Wuxi cities, said an airport spokesman.

The airport had resumed operations and more details would be revealed after an investigation, he said.
