Amnesty International is urging the Greek government to scrap a controversial arms sale to Saudi Arabia, saying the weapons could be used against civilians in the ongoing war in Yemen, AP reports. The rights organization voiced deep concern Monday over the proposed deal, saying there was a “real danger” that the artillery shells would be used by the Saudi-led Arab coalition fighting Shiite rebels. The agreement has been strongly criticized by Greek opposition parties. At least two lawmakers in the governing left-wing Syriza party have called for its cancellation on grounds that the arms could be used in Yemen.
