Sri Lankan says suspected wartime mass grave is an old cemetery

COLOMBO (Reuters) - Officials investigating a suspected mass grave in Sri Lanka's former northern war zone called off the digging on Friday because the 83 skeletons unearthed there seem to have been buried in an old cemetery.

The Sri Lankan army has been accused of killing tens of thousands of civilians in the final weeks of its 26-year war against northern Tamil separatists in 2009 and Colombo has been under pressure to investigate reports of mass graves there.
