Iran cleaning up nukes?

Concerns continue to grow with Iran: Satellite images of an Iranian
military facility show trucks and earth-moving vehicles at the site,
indicating that crews were trying to clean it of radioactive traces
possibly left by tests of a nuclear-weapon trigger. The assertions,
which came from diplomats, all nuclear experts accredited to the
International Atomic Energy Agency, could add to the growing
international pressure on Iran over its nuclear program, which Tehran
insists is for peaceful purposes. An Israeli official claims satellite
images that raised suspicions Iran is trying to conceal a key nuclear
test, back Israel's concerns that Tehran is developing an atomic bomb.
While the US and the EU are backing a sanctions-heavy approach, Israel
has warned that it may resort to a pre-emptive strike against Iran's
nuclear facilities to prevent it from obtaining atomic weapons.
