特朗普威胁导弹袭击叙利亚

The World Health Organization said Wednesday it had received reports from its partners about the victims. The WHO said 500 people who sought treatment Saturday showed signs and symptoms of coming in contact with toxic chemicals. A WHO spokesman said, however, the agency cannot say the deadly incident was a chemical attack because it cannot get into the area.

The WHO said it had reports that as many as 70 people may have died.

The U.N. agency demanded that it be given the "immediate, unhindered" ability to meet with people injured in the attack.

The United States and several allies have centered blame on military forces loyal to President Bashar al-Assad. But Syria and Russia have denied that charge.

Trump also has blamed supporters of Assad in Iran and Russia for the attack.

Soon after the suspected gas attack, Trump said those responsible would pay a "big price." The U.S. president has spoken with the leaders of Britain and France about a possible answer.

French President Emmanuel Macron said a decision on a possible strike would be made "in the coming days."

The United Nations Security Council met on Tuesday for an urgent discussion on Syria. Russia vetoed a U.S.-proposed measure to create a commission to investigate the attack.

The Associated Press reports that the Organization for the Prohibition of Chemical Weapons (OPCW) will send a fact-finding group to Douma "shortly." The OPCW is based in The Hague.

The AP says the Syrian government and Russian supporters requested the mission. However, it is unclear if such a mission might affect U.S. or allied military action in the area.

The U.S. has more than 2,000 troops in Syria, and the U.S.-led coalition has launched thousands of airstrikes against the country. Most have been against the Islamic State terror group.

President Trump has cancelled a planned trip to Latin America, which was to begin Friday. The administration said that Trump would "oversee the American response to Syria."
