Russia

President Vladimir Putin was one of the first world leaders who publicly condemned the La Ramblas van attack that left 14 dead.

“We strongly condemn this cruel and cynical crime perpetrated against ordinary citizens,” Putin said in a statement while offering his condolences to Spaniards and the King of Spain, Felipe VI. He underlined that Barcelona’s terror attack “reaffirms once again the need to truly unite the efforts of the entire international community in the fight against terrorist forces.”

Putin's message to the Spanish people followed reaction by Russia's foreign ministry.

Решительно осуждаем теракт в #Barcelona. Уверены, этому злу нет оправдания. Передаём слова сочувствия народу Испании. Скорбим вместе с вами — МИД России 🇷🇺 (@MID_RF) August 17, 2017

“We strongly condemn the terrorist attack in Barcelona, and we are sure that there is no justification for this evil,” the ministry said on Twitter.

“We convey the words of sympathy to the people of Spain. We mourn together with you.”

USA

Reaction from US President Donald Trump has meanwhile sparked some criticism. While initially condemning the terrorist attack in Barcelona and offering to “do whatever is necessary to help,” Trump in his next tweet, advised his followers to, “study what General Pershing of the United States did to terrorists when caught. There was no more Radical Islamic Terror for 35 years!”

While Trump did not clarify what he meant, the US general Pershing Trump was referring to, fought in the Moro uprising in the Philippines and allegedly shot prisoners with bullets "dipped in pig's blood." Many critics pointed out though that the claim is false.

Following Islamic State’s (IS, formerly ISIS/ISIL) claim of responsibility for the Barcelona massacre, Brett McGurk, the special presidential envoy for the US-led coalition to defeat the terror group pledged the “unwavering resolve of our entire coalition to destroy ISIS.”

“Parisians are at your side,” Hidalgo tweeted. “Barcelona and Paris are cities that share love and tolerance. Our values are much stronger than this heinous and cowardly act of terrorism.”
