US Senate approves legislation on Iran sanctions

US Senate approved legislation that would impose sanctions on Iran's gasoline suppliers and penalize some of Tehran's elites, a move aimed at pressuring Tehran to give up its nuclear program.The sanctions, approved on a voice vote, would target companies that export gasoline to Iran or help expand the country's oil-refining capacity by, in part, denying them loans and other assistance from US financial institutions. Lawmakers and the Obama administration fear Iran's uranium enrichment program will be used to develop weapons, while Tehran says it is for peaceful purposes such as generating electricity. While on the other side US has decided to keep 7 billion dollars budget for enhancement of the nuclear weapons.
