Letters containing white powder were sent to the UN missions of France, Austria and Uzbekistan in New York City on Monday, police said.

About 40 people were decontaminated as a precaution, the majority of which were working at the French mission, a N.Y. Police Department spokesman told Reuters.
He said the white powder from each of the letters, which were received between 4 p.m. and 6:30 p.m. EST (2100 and 2330 GMT), was being tested and that investigations were continuing.
No further details were available.
