The EU foreign policy chief spoke to his Iranian counterpart condemning the execution of foreign nationals.

Josep Borrell said in a tweet on Monday that he has discussed the recent execution of Swedish-Iranian national Habib Chaaband and urged Iran not to execute German-Iranian Jamshid Sharmahd.

Speaking with Hossein Amir-Abdollahian over the phone, he said the pair discussed Iran-IAEA cooperation, which he said had gained momentum recently.

“I stressed that Iran must continue this, end support to Russia’s war against UA, and stop instrumentalizing EU nationals,” he wrote.

Iran executed Iranian-Swedish political activist and former leader of the Arab Struggle Movement for the Liberation of Ahwaz (ASMLA) Habib Chaab (Asyud) on Saturday for “corruption on earth”.

Chaab, 49, was put on trial by a revolutionary court in Tehran in December. He was not allowed to choose his own defense attorney and was represented in his trial by a court-appointed lawyer. He was also forced under duress to make self-incriminating confessions.

Iranian authorities say Chaab was found guilty of leading ASMLA (Harakat al-Nidal in Arabic), a movement which advocates the separation of southwestern Khuzestan Province and for plotting "numerous bombings and terrorist operations" in the oil-rich province with a large Arabic speaking population.

In less than 48 hours, two Iranians jailed for insulting religious entities were also hanged amid global outrage and a killing spree which has seen around 200 executions this year so far.
