The attack took place late Sunday night when four IS militants attacked a military position manned by a government-backed paramilitary Sunni group known as Sahwa in the al-Radwaniyah area, Xinhua news agency quoted the media office of the Joint Operations Command (JOC) as saying in a statement.
One of the three injured left the hospital after receiving treatment, the statement added, without giving further details.
