(CNN) -- Two rockets landed inside the heavily fortified Green Zone in Baghdad, home of the US Embassy in Iraq, on Wednesday afternoon, according to the Iraqi military. The Iraqi joint military command told CNN in Baghdad that "two Katyusha rockets landed inside the Green Zone in Baghdad. No reports of casualties. " The incident took place just after midnight local time. The CNN team in Baghdad heard sirens from inside the Green Zone and two explosions. It was not immediately clear who had fired the rockets or where they were fired from. The rockets landed a day after Iran fired more than a dozen missiles at Iraqi bases housing US troops. The attack on Tuesday from Iran did not cause any US or Iraqi casualties.
