President Barack Obama called for the United Nations' Security Council to impose sanctions against Syrian President Bashar al-Assad and his regime for their bloody crackdown on political dissent. Mr. Obama said before the U.N. General Assembly Wednesday that the Syrian people have shown dignity and courage in their pursuit of justice "protesting peacefully, standing silently in the streets, dying for the same values that this institution is supposed to stand for. The question for us is clear: Will we stand with the Syrian people, or with their oppressors?" according to a text of his prepared remarks. "Now is the time for the United Nations Security Council to sanction the Syrian regime, and to stand with the Syrian people," Mr. Obama said. The U.S. has already imposed sanctions against Syria.
