Three Katyusha rockets fell on Wednesday inside Baghdad’s heavily fortified Green Zone which houses government buildings and foreign missions, causing a fire, Iraqi police sources told Reuters.

Sirens were sounding inside the Green Zone, and at least one of the rockets fell 100 metres away from the U.S. embassy, the sources said.

NOTE (Ed): Katyushas are lower-tech rockets, and militias have used them to target the Green Zone and the airport on a fairly regular basis.
