The US on Friday said it was imposing visa restrictions on 13 Iranian officials it accused of involvement in "gross violations of human rights" for a 1990 assassination of an Iranian opposition figure in Switzerland.
The State Department did not name the 13, but in a statement said it was also designating a 14th Iranian, Hojatollah Khodaei Souri, who it said as director of Iran's Evin Prison ran an institution "synonymous with torture and other cruel, inhuman, or degrading treatment or punishment."

"The United States will continue to pressure Iran to treat its own people with dignity and respect," US Secretary of State Mike Pompeo said.
