The Iraqi military said in a statement that Monday’s rocket attack was planned to be a larger one as security forces found launchers that had not been fired properly.
Those wounded in the assault belonged to Iraq’s Counter-Terrorism Service, security sources told AFP, adding two of them were in critical condition.
The base also houses a small group of US soldiers and American diplomats.
Attacks on Iraqi bases hosting US troops and foreign diplomatic missions come as a wave of protests over unemployment, corruption and lack of public services continue in the country.
