The Indian High Commissioner to Sri Lanka, YK Sinha, has formally handed over an Indian coast guard ship to Sri Lanka's navy.

The ship was initially given to Sri Lanka in 2006 " in appreciation of the Sri Lanka Navy’s efforts to maintain the maritime security in the region", the Daily Mirror reported.

Defence Ministry Secretary B Basnayake accepted the ship on behalf of the Sri Lankan government.

Sri Lanka's navy is regularly accused of attacking Indian fishermen from Tamil Nadu, worsening an already tense diplomatic relationship with the southern Indian state.

Tamil farmers and agricultural workers from Kilinochchi and Mullaitivu protested on Monday that over 90% of newly appointed agricultural research assistants to the North are Sinhalese.

The US announced on Wednesday it would support the Sri Lankan government in creating a credible domestic process to address accountability and reconciliation.

Speaking to reporters, US assistant secretary of state for South and Central Asian Affairs Nisha Biswal said "We support efforts to create a credible domestic process for accountability and reconciliation."

"The failure of past efforts is very much on our minds, but that is why you have to emphasise on building trust."

“We have recognised that there is a different opportunity that exists today and a different landscape for trying to advance reconciliation,” Ms Biswal further said. “We look forward to a process in Geneva that allows an opportunity to reflect on that.”

The assistant secretary said the US would propose a resolution at the UN Human Rights Council next month and hoped that Sri Lanka would collaborate. She said the thrust of the resolution would be decided after reviewing the final report of the OHCHR Inquiry in Sri Lanka, which is expected to find that tens of thousands of Tamil civilians were killed in the last phase of the armed conflict alone.
