We found the weapons of mass destruction. Sort of.

ABCNews has learned that United Nations weapons inspectors discovered six to eight vials of a dangerous nerve gas, phosgene, as they were cleaning out offices at a U.N. building in New York Thursday morning…

Authorities said the phosgene was believed to have been discovered in Iraq and manufactured prior to 1991.

Former U.N. weapons inspectors told ABCNews.com that vials of phosgene had also been used by inspectors in Iraq to help calibrate air sampling instruments.

The former inspectors said the remaining vials were supposed to have been destroyed…

“They need to get it out of there and put it in a safe canister,” [former New York City emergency services director Jerry] Hauer said. “It shows immense stupidity to have that kind of thing sitting around as a souvenir.”…

According to an article in Foreign Affairs, the chemical was allegedly used by Iran in the Iran-Iraq war in 1987.

Update: On the premises for 11 years.
