American forces fired tear gas on protesters Wednesday, a day after a large group of militia stormed and breached the gates of the U.S. Embassy in Baghdad.

Tuesday, protesters breached the embassy compound walls, chanted "Death to America" and set small fires on the premises. The militia fighters stayed outside the facility Tuesday night.

Wednesday, the group lit a fire on the roof of the reception area, The Associated Press reported, per ABC News, which prompted a response from the U.S. military.

The New York Times reported that a group of protesters, much smaller than Tuesday's demonstration, tried to climb on the roof of the guard post and jump inside the compound. This move also prompted American forces to fire tear gas.

The Times reported that an even larger number of demonstrators attempted to climb the roof at around midday but were stymied by yet another round — about four volleys — of tear gas, finally pushing the protestors back from the compound's front gate.

An Iraqi general deployed to the area said, "This is not good — they have to stay away from the wall," adding that American forces "are right when they fire tear gas because otherwise the protesters will get inside the compound, but we are caught in between," according to the news source.

Wednesday's outbursts follow a protest that broke out Tuesday, when the group of Iranian-backed militia stormed the U.S. Embassy in Baghdad in response to previous airstrikes by the U.S. military targeting Kataib Hezbollah groups in Syria and Iraq. The strikes killed 25 militia fighters.
