According to AFP:
Hassan Rouhani on Saturday postponed what would have been the first visit to Europe by an Iranian president in 10 years after attacks in Paris that he described as "crimes against humanity."
Foreign Minister Mohammad Javad Zarif, who had been due to travel with Rouhani, told state television he would now instead head Iran's delegation to international talks on the Syrian conflict in Vienna.
Rouhani sent a message of condolence to French counterpart Francois Hollande on the shootings and bombings in Paris that left more than 120 people dead, Iran's official IRNA news agency reported.
"In the name of the Iranian people, who have themselves been victims of terrorism, I strongly condemn these crimes against humanity and offer my condolences to the grieving French people and government," Rouhani said.
Zarif said the Paris attacks made the Vienna talks all the more important as world governments needed to work together to fight against the Islamic State group and other extremists.
"We must use the opportunity presented by these crimes to coordinate internationally," he said.
"The Paris events show once again that terrorism and extremism are an international threat and that international cooperation is necessary to fight this phenomenon."COMMENTARY: Beirut was bombed two days ago, Paris yesterday and Baghdad today.
This writer stated at the onset of the 2014 Northern Iraq Offensive carried out by ISIL that regional rivalries between the United States and Iran should be set aside, with priority given towards the defeat of ISIL. This writer also pointed out the danger to Europe and particularly France, to Salafi Jihadist terror. Unfortunately the rivalry went on unabated and the terror strikes materialized.
The Russians and Iranians are currently engaged in an effective military campaign against armed Salafi Jihadists in Syria. It is hoped the parallel tracks of the U.S.-led coalition against ISIL can be made unified with that of the Russo-Iranian-Syrian-Iraqi-Lebanese alliance. That way forward offers the best prospect of defeating this threat, while the parallel track approach has proven highly inefficient.
The United States and Russia have reportedly exchanged preliminary lists of what they regard as terrorist groups in Syria. That's a positive step that should be built upon.
