VIENNA- Iran is enriching uranium to 4.5% fissile purity, above the 3.67% limit set by its deal with major powers, the U.N. nuclear watchdog policing the deal told member states in a closed-door meeting on Wednesday, diplomats familiar with the figures said.

The International Atomic Energy Agency had previously only said Iran was over the 3.67% limit. It also said on Wednesday that Iran's stock of enriched uranium was now 213.5 kg, over the deal's 202.8 kg limit, and more than the 205 kg verified on July 1. 

Both figures were verified on Tuesday, the three diplomats said.
