Two Katyusha rockets have reportedly landed in the heavily fortified Green Zone in Iraq's capital of Baghdad, but there no-one was injured, according to Reuters.

A day earlier, Iran struck back at the United States for killing its most powerful military commander, firing a barrage of ballistic missiles at two Iraqi military bases that house American troops.

US President Donald Trump later said Iran "appears to be standing down" and credited an early warning system "that worked very well" for the fact that no Americans or Iraqis were killed. He said damage was also minimal.
