Five people illegally entered the premises of Iran's embassy in Stockholm during a protest on January 23, Swedish police said. The people were later removed from the area. It was not immediately clear whether any of the five had entered the embassy building itself, a police spokesperson told the TT news agency. Stockholm and Tehran are involved in a growing diplomatic row over several Swedish citizens held in custody in Iran. Tehran has meanwhile accused a Swedish court of unjustly sentencing a former Iranian official to life in prison over a mass execution of political prisoners in the 1980s.
