Britain on Friday recalled the brutality of the Tamil Tiger rebels which fought the Sri Lankan army for 30 years.

British Deputy High Commissioner to Sri Lanka, Robbie Bulloch was quoted in a High Commission statement as saying Britain will continue to support Sri Lanka in building a sustainable peace in all parts of the country.

Bulloch visited the north and east of the country over the past few days including a naval base in the east and former Tamil Tiger bases and areas where the final stages of the war took place between the military and the rebels before the rebels were defeated in 2009.

The British High Commission said that the Deputy High Commissioner saw at first hand the devastation caused by the conflict, including through meeting displaced people and war affected Tamil, Muslim and Sinhalese communities.

"We saw some good work being carried out to help resettle former internally displaced communities and restore their livelihoods, as well as important infrastructure development. We also learned more about the brutality of the Tamil Tiger rebels, which used child soldiers and committed terrorist atrocities," the Deputy High Commissioner said in the statement.

He noted that despite the end of the war challenges still clearly remain, including the promotion of long term reconciliation between people whose memories of a violent conflict are in many cases still fresh.

"The UK will continue to support Sri Lanka in building a sustainable peace in all parts of the country," he said.

Britain was among the countries which called for an independent investigation in Sri Lanka into the alleged human rights abuses committed during the final stages of the conflict.
