Iraqi security forces stand guard in front of the U.S. embassy in Baghdad, Iraq, Wednesday, January 1, 2020. U.S. troops fired tear gas on Wednesday to disperse pro-Iran protesters who were gathered outside the U.S. Embassy compound in Baghdad for a second day. Dozens of pro-Iranian militiamen and their supporters had camped out overnight at the gates of the embassy in Baghdad. On Tuesday, dozens of protesters broke into the compound, trashing a reception area and smashing windows in one of the worst attacks on the embassy in recent memory.
