This photo released by the government-affiliated Media Security Cell on Thursday, March 12, 2020, shows a rocket-rigged truck launcher after a rocket attack on Camp Taji, a few miles north of Baghdad, in Rashidiya, Iraq. Iraq’s military on Thursday said it opened an investigation into the rocket attack that hours earlier killed three servicemen, including two Americans, at an Iraqi base housing coalition forces that has been used as a training base for a number of years.
