Spanish fighters fighting against the Islamic State group in Raqqa with the International Brigade of the Kurdish People’s Protection Units (YPG) have released a statement on the attack carried out in Barcelona in which 13 people were killed.

Fighters from countries around the world have joined the YPG in its fight against ISIS in northern Syria.

Siyar Santucho, a fighter from Spain’s capital Madrid, said the YPG were getting very close to liberating the city of Raqqa, the Islamic State’s so-called capital. “I would like for everyone to know that it is for incidents such as the one the people of Barcelona suffered in the past few days that we are here in this city. We are here against the fascism of ISIS.”

Kemal Amed, a fighter from the Basque Country, said that he and his fellow comrades would avenge the attack against Barcelona by making sure ISIS has no haven in Syria. “ISIS is trying to cover its losses by attacking innocent civilians. We want everyone affected by the events in Barcelona to know that ISIS will pay for every atrocity they have committed.”
