Senator calls for more Iran sanctions

BUSHEHR, IRAN - AUGUST 21: This handout image supplied by the IIPA (Iran International Photo Agency) shows a view of the reactor building at the Russian-built Bushehr nuclear power plant as the first fuel is loaded, on August 21, 2010 in Bushehr, southern Iran. The Russiian built and operated nuclear power station has taken 35 years to build due to a series of sanctions imposed by the United Nations. The move has satisfied International concerns that Iran were intending to produce a nuclear weapon, but the facility's uranium fuel will fall well below the enrichment level needed for weapons-grade uranium. The plant is likely to begin electrictity production in a month. (Photo by IIPA via Getty Images)
