Pentagon officials say the U.S. is investigating the role that Russia may have played in Syria's chemical weapons attack on its own civilians earlier this week. According to an Associated Press report, a drone that belonged to either Russia or Syria was seen hovering over the site on Tuesday after the attack, which killed more than 80 people, including at least 20 children. That same drone reportedly returned to the area later, just before a hospital was bombed. The hospital raid was allegedly an attempt at covering up evidence of the chemical attack, according to AP sources.
