Newly revealed satellite images show Iran may have been testing triggers for nuclear weapons.

The images -- obtained by the United Nations' International Atomic Energy Agency on Wednesday -- show Iranian trucks and earth movers trying to clean up what appears to be radioactive waste at Iran's Parchin military site.

One Israeli official told The Associated Press the only purpose of that trigger test is to develop nuclear arms.

The official, speaking on the condition of anonymity, said the pictures "reinforce what Israel has been saying all along. the Iranian nuclear program is not benign."

Iran has just agreed to allow inspections of the site they've been cleaning. The Islamic Republic claims they are developing nuclear power for peaceful purposes, a claim rejected by Israel and the West.
