The European Union's foreign ministers will discuss more sanctions against Iran during their meeting today (Monday).
German Foreign Minister Annalena Baerbock announced the decision, adding that more members of the Revolutionary Guard will be sanctioned.
In response to Iran's human rights violations, Baerbock told journalists, "We won't accept this."
On Friday, the European Union condemned Iran's execution of three men linked to protests sparked by Mahsa Amini's death last year.
“The EU urges the Iranian authorities to refrain from applying the death penalty and carrying out future executions,” EU foreign policy chief Josep Borrell’s office said in a statement.
According to the EU statement, Iranian officials must respect the "due process rights" of detained individuals and prevent them from being mistreated.
Additionally, it called on Iran to respect "the freedom of expression and peaceful assembly rights," which are enshrined in international law.
The Islamic Republic executed Majid Kazemi, Saeed Yaghoubi and Saleh Mirhashemi on Friday morning over trumped up charges after extracting forced confessions, in a case described as a travesty of justice. Human rights campaigners say they were tortured into confessions, and there was no reliable evidence against them.
Friday's executions brought to at least seven the number of protesters hanged since the beginning of the nationwide protests last September, which turned into one of the boldest challenges to the clerical rulers since the 1979 revolution.
Iranian authorities brutally suppressed protests that erupted in Tehran after the death in custody of Amini, a 22-year-old Iranian Kurd arrested in Tehran for allegedly violating the country's strict dress code.
