Rogue US soldier accused of killing 16 Afghan civilians on his way to US military base An unnamed US official had told The New York Times the killings were a result of "a combination of stress, alcohol and domestic issues - he just snapped." But Mr Browne said suggestions of marital problems were "totally bogus." He said his client has a "very strong marriage and frankly we're all taking offense at that." Mr Browne said he had heard from a military lawyer that "another soldier at this base was brutally attacked the day before this incident and actually had his leg shot off right in front of my client." Asked whether the massacre may have involved more than one soldier, Browne said: "I don't have any information on that, one way or the other." Mr Karzai met with village elders and families of victims of the shootings on Friday and appeared to back their belief that one gunman acting alone could not have killed so many people and in different places some distance apart. On Thursday, Mr Karzai called for NATO troops to leave Afghan villages and confine themselves to major bases, underscoring fury over the massacre and clouding US plans to withdraw its troops from Afghanistan by the end of 2014.
