Washington, Oct 29 : Six children aged one to 13 were killed in an apparent murder-suicide in the US state of Oklahoma, police said. The bodies were recovered from a residence in Broken Arrow, a suburban city about 15 miles southeast of downtown Tulsa, reports Xinhua news agency. Two adult suspects were also found deceased in the home, Broken Arrow Police Chief Brandon Berryhill said at a news conference on Friday, adding that guns have also been recovered. "At this time we do not believe that any of the victims died from the fire, however the final determination for the cause of death will be made by the medical examiner," Broken Arrow Fire Chief Jeremy Moore said. A blaze erupted on Thursday afternoon in the rear of the home, and fire crews responded within minutes and found the bodies inside, said Moore. The victims have not been identified and a probe is underway to determine the exact cause of death. /IANS
