(CNN)Iran fired a number of missiles at two Iraqi bases housing US troops Wednesday in retaliation for the American strike that killed a top Iranian general last week.
The early morning attack presents President Donald Trump with the biggest test of his presidency to date.
A US official told CNN that there were no initial reports of any US casualties from the attack, but an assessment of the impact of the strikes is underway. Iraq's joint military command said there were no casualties among Iraqi military forces.
There is a growing belief among some administration officials that Iran's missiles intentionally missed areas populated by Americans when they targeted the two Iraqi bases, multiple administration officials said.
These officials floated the notion that Iran could have directed their missiles to hit areas that are populated by Americans, but intentionally did not.
