Two activists from a Gaza-bound flotilla, arrested off the coast of Greece, have been brought to Israel for questioning, a move Spain has condemned as "illegal". The flotilla of more than 50 vessels had set sail from France, Spain and Italy with the aim of breaking an Israeli blockade of Gaza and bringing supplies to the devastated Palestinian territory. They were intercepted by Israeli forces in international waters off Greece early on Thursday, with Israel saying it had removed some 175 activists -- two of whom were taken to Israel for questioning.
