Eight US soldiers died in two separate attacks in Diyala province, and two more were killed by a roadside bomb in southern Baghdad on Memorial Day.
Two pilots of Task Force Lightning were killed when their OH-58 Kiowa Warrior helicopter went down north of Baghdad, Reuters reports as a result of hostile fire, though the AP writes that it is unclear if the helicopter was shot down or suffered mechanical failure.
The US military press release says that six more Task Force Lightning soldiers were killed when roadside bombs exploded near their vehicles while they were conducting operations in Diyala. Reuters reports that the quick reaction force was en route to the helicopter crash site when the attack occurred.
According to CNN, the helicopter was flying an observation mission over a major supply route between Baquba and Mahmoudiya when their wingman--on a Kiowa flying nearby -- reported heavy machine-gun fire in the area.
After the helicopter went down, a quick-reaction force was called in to recover it, a military official told CNN, and two Bradley fighting vehicles were blown up by roadside bombs.
Air assault forces then came in by helicopter, recovered the bodies of the two pilots and destroyed the downed chopper.
The US military said three soldiers wounded in the attack on the QRF convoy were evacuated to a Coalition medical facility.
The names of the deceased are being withheld pending notification of next of kin and release by the Department of Defense.
