Khamenei Slams Republican Letter on Iran, U.S. Known for 'deceit'

Iran's Supreme Leader hit out on Thursday at a letter by U.S. Republican senators threatening to undo any nuclear deal between Washington and Tehran, saying he was worried because the United States was known for "backstabbing", Mehr news agency reported.
Ayatollah Ali Khamenei added at a meeting with President Hassan Rouhani and senior clerics that whenever negotiators made progress, the Americans became "harsher, tougher and coarser", Mehr reported.
The letter signed by 47 Republican senators warned Iran that any nuclear deal made with U.S. President Barack Obama could last only as long as he remained in office, in an unusual intervention into U.S. foreign policy-making.
Mehr quoted Khamenei as saying: "Of course I am worried, because the other side is known for opacity, deceit and backstabbing."
