US senators urge Obama to take firm stance on Iran

A group of US senators have urged President Barack Obama to take a firm stance on Iran amid ongoing nuclear negotiations.

According to Press TV, the Saturday letter from 22 Democratic senators and one independent hailed Obama’s two-track approach to Iran, which incorporates both sanctions and negotiations.

The letter, issued from the office of Senator Carl Levin, called for tough procedures of transparency and verification, which guarantee non-diversion in Iran’s nuclear energy program.

The majority of the 23 senators had declined to sign another letter issued by 83 of their colleagues earlier this week.

That letter, initiated by Democrat Senator Robert Menendez, insisted that any final nuclear agreement with Iran must stipulate that Tehran “has no inherent right to enrichment under the Non-Proliferation Treaty.”

Iran has repeatedly said that its enrichment rights are non-negotiable.
