Senior Superintendent of Police Ajith Rohana said the remains had been found in the garden of the house at Puthukudyiruppu in Mullaithivu district which served as the LTTE's military capital.
"Skulls of at least nine people were found on Thursday in evening during the clearing work of the garden. The parts have been taken away by the Judicial Medical Officer of the Jaffna hospital for further investigations," Rohana said.
Reacting to the discovery, the military said the remains could be secret burials by the LTTE. "It is a well known fact that the LTTE did all they could to hide deaths in order to prevent people uprising and maintain their cadre's morale high. The skeletal remains found recently near a former LTTE held area could very well be such dead buried secretly," military spokesman Brigadier Ruwan Wanigasooriya said.
Nine bodies were recovered from the family's garden
He said by the early 2009 the LTTE had one of their defences in this area. They were desperately trying to stop the advancing government troops and killed those who defied their orders.
The area was under the control of the Tamil Tigers for over 20 years. The fall of Puthukudyiruppu was a significant milestone in the crushing defeat of the LTTE. All top LTTE leaders, including its chief V Prabakaran, were residents as the Army advanced into the area in the final military battle in early 2009.
The finding comes close on the heels of the discovery of at least two mass graves, one in the northern district of Mannar and the other in the central district of Matale.
Sri Lanka is currently under the focus of the international community for alleged war crimes during the final battle with the LTTE. The US plans to move a third Sri Lanka resolution this month at the UN Human Rights Council which is likely to call for an independent international probe.
