Mystery package prompts consulate closure

Visa services have been suspended at the US consulate in Guangzhou, capital of Guangdong province, after it received a bag of unidentified white powder on Monday.

"Visa services will only resume once the incident has been fully investigated," a spokesman for the consulate said on Tuesday on condition of anonymity.

"The source and identity of the unidentified material is now under police investigation," the official added.
