The defense system was installed by the U.S. over the summer as armed groups stepped up rocket attacks targeting the embassy and its premises.
The U.S. withdrew some staff from its embassy in Baghdad earlier this month, temporarily reducing personnel ahead of the first anniversary of the U.S. airstrike that killed Iran's top general, Qassim Soleimani, outside Baghdad's airport on Jan. 3. American officials said the reduction stemmed from concerns about a possible retaliatory strike.
Soleimani's killing sparked outrage and led Iraq's parliament to pass a non-binding resolution days later calling for the expulsion of all foreign troops from Iraq.
A sudden attack, typically a military one.
The People's Liberation Army is developing precision-strike capabilities.
