UNITED NATIONS- UN Secretary-General Ban Ki-moon said on Tuesday that the use of force is only legal when it is in self-defense or with UN Security Council authorization, remarks that appear to question the legality of US plans to strike Syria without UN backing.
He said that if UN inspectors confirm the use of chemical weapons in Syria, the Security Council, which has long been deadlocked on the 2-1/2-year Syrian civil war, should overcome its differences and take action.
"If confirmed, any use of chemical weapons by anyone under any circumstances will be a serious violation of international law and outrageous war crime," he told reporters. "Any perpetrators must be brought to justice. There should be no impunity."
