Iran executed Iranian-German national Jamshid Sharmahd after he was convicted of carrying out terrorist attacks, Iranian state media said on Monday.

       Sharmahd, who also holds U.S. residency, was sentenced to death in 2023 on charges of "corruption on earth", a capital offence under Iran's Islamic laws.

       He was accused by Iran of heading a pro-monarchist group accused of a deadly 2008 bombing and planning other attacks in the country.

       Sharmahd's arrest was announced in 2020 in an intelligence ministry statement that described him as "the ringleader of the terrorist Tondar group, who directed armed and terrorist acts in Iran from America."

       Based in Los Angeles, the little-known Kingdom Assembly of Iran, or Tondar, says it seeks to restore the Iranian monarchy that was overthrown by the 1979 Islamic revolution. It runs pro-Iranian opposition radio and television stations abroad.

       "The execution of the death sentence against our fellow citizen Jamshid Sharmahd is a heinous crime," the leader of the Christian Democrats CDU in Germany, Friedrich Merz, told Reuters on Monday.

       The opposition leader asked the German government to respond decisively, saying that the approach of "quiet diplomacy" had failed.

       "Relations with Iran should be put to the test in view of the state-sponsored killing of a German citizen," Merz said. "The Iranian ambassador must be expelled." REUTERS
