ElBaradei arrives in Tehran
Head of the United Nations nuclear enforcement agency Mohamed ElBaradei arrived in Tehran to negotiate a timetable for when international inspectors will be allowed to enter an underground uranium enrichment plant Iran had kept secret for years.

In a meeting with world powers this week in Geneva, Iran, which is facing growing Western pressure over its nuclear program, pledged to grant inspectors from the International Atomic Energy Agency access to the plant within weeks. The facility is expected to house 3,000 centrifuges for enriching uranium and complement the nation's main nuclear plant at Natanz.
