Iranian leader Ali Khamenei called the US sanctions a crime against Iran.
His remarks came on Friday amid Washington's expansion of restrictive measures against Iranian nuclear, missile and military programs, TASS reported.
The spiritual leader added that in the face of proposals for talks, Iran should not make concessions. If the US conditions are accepted, they will set new ones, he noted.
Secretary of State Mike Pompeo said Thursday that Washington is expanding sanctions on Tehran.
According to him, additional restrictions are intended to prevent the supply of products to Iran that can be used in the implementation of nuclear, missile, and military programs.
