It's hard to tell what's going on.  This BBC report from earlier says at least 3 soldiers dead in
 an incident in Khaldiyah,  though the military hasn't yet commented on this situation.  They are however stating that 3 soldiers have died in what seems to be a 
separate incident in Tikrit.  We also have another soldier falling victim to a "
non-hostile gunshot incident," and another killed 
by a power line.  There are also several reports of soldiers being wounded.
