"It is vitally important that Iran be called to account for its deplorable human rights record, including egregious violations of religious freedom," the US Commission on International Religious Freedom (USCIRF) wrote in a letter to Clinton.

"The United States must signal during the current talks its unwavering support for Human Rights for all Iranians and insist that Iran honor its international obligations on religious freedom," read the letter.

The bipartisan federal agency USCIRF was established in 1998 and monitors global religious freedom to offer independent policy recommendations to senior US officials, including the president and Congress.
