In a statement on Wednesday, the resistance movement said, “The ongoing terror attacks across the globe have their roots in ideologies that are being nurtured and supported by certain countries. These countries use it for their own political and economic agenda.”

The statement added, “The key in the fight against terrorism is to stand up to Saudi Arabia and curb its ideology of Wahhabism. It is also important to stand up to Turkey because of its support for ISIL.”

At least 36 people were killed and well over 200 others wounded in a series of bomb attacks in the Belgian capital on Tuesday, where ISIL bombers targeted the airport with a pair of suicide blasts, and subsequently bombed a subway train at Maelbeek station, near the EU headquarters.

There appear to have been three bombers at the Brussels Airport, two of them killed as suicide bombers, and the other leaving a nail-bomb and leaving the airport. He is still at large, and authorities recovered his bomb, which never detonated.

The deadliest attack came an hour after the airport bombings, however, when a man opened fire in a subway train before detonating, killing over 20 people. Officials say they recovered a Kalashnikov rifle from the scene.

Brussels has been under virtual lockdown since then, with the airport closed, and all public transportation shut down. The Eurostar train system, despite not being targeted, has similarly been shut down in the wake of the attacks.

Several nations have offered travel warnings against going to Brussels since then, and indeed it would be difficult to do so even if one was of a mind to. The fear of more ISIS attacks is spreading far beyond Brussels, however.

The seemingly co-ordinated attacks in Brussels come only a day after Jan Jambon, Belgium’s interior minister, warned that jihadis could be looking to counter-attack after the arrest last week of Salah Abdeslam, a suspected leader of November’s Paris terror attacks.

The Iranian foreign ministry deplored the Tuesday multiple terrorist attacks in Brussels which killed several innocent people, and stressed the need for united efforts to fight terrorism.

Foreign Ministry Spokesman Hossein Jaberi Ansari condemned the blasts, and sympathized with the Belgian nation and government, specially the bereaved families of victims.

“Continued terrorist operations in different parts of the world shows that terrorism and extremism are common threats to the entire world, and indicate the necessity for integrated and comprehensive confrontation against this ominous phenomenon and the centers which support them politically, ideologically and financially,” he added.
