I will not trust 'el mundo' too much in this case, it is known for its 'creative' writting. In any case the spanish government seems to be very alarmed with this situation, maybe because comparatively they did very few, really late, and with obvious discomfort for protecting the people in distress.
Just a personal opinion. I will not expect a lot of support for Varufakis or Greece in official newspapers or public spanish TV just right now.
“What they’re doing with Greece has a name: terrorism,” Varoufakis told Spain’s El Mundo. “What Brussels and the troika want today is for the yes [vote] to win so they could humiliate the Greeks. Why did they force us to close the banks? To instil fear in people. And spreading fear is called terrorism.”
"Lo que están haciendo con Grecia tiene un nombre: terrorismo."
I dont speak spanish, and i guess the interview was in english, but reading the ensuing dialog its clear he said terrorism.
