Iran reportedly cleaning up nuclear work

Satellite images of an Iranian military facility appear to show trucks and earth-moving vehicles at the site, indicating an attempted cleanup radioactive traces possibly left by tests of a nuclear-weapon trigger, diplomats told The Associated Press on Wednesday.

Two of the diplomats said the crews may be trying to erase evidence of tests of a small experimental neutron device used to set off a nuclear explosion. A third diplomat could not confirm that but said any attempt to trigger a so-called neutron initiator at the Parchin site could only be in the context of trying to develop nuclear arms.

The images, provided to the IAEA by member countries, are recent and constantly updated, said one of the diplomats.

The diplomats are nuclear experts accredited to the International Atomic Energy Agency. All asked for anonymity to discuss sensitive information.

Iran is under growing international pressure over its nuclear program, which it insists is peaceful. Israel has warned that it may resort to a pre-emptive strike against Iran's nuclear facilities to prevent Tehran from obtaining atomic weapons.

The IAEA has already identified the Parchin military site as the location of suspected nuclear weapons-related testing. In a November report, it said it appeared to be the site of experiments with conventional high explosives meant to initiate a nuclear chain reaction.
