Prime Minister Manmohan Singh has said that India is committed to working on a 'priority basis' for the relief and rehabilitation of IDPs in Sri Lanka and New Delhi has conveyed its concerns on the issue to the island government in "no uncertain terms", reported PTI.

"We fully share your concern for the welfare and well-being of the displaced Tamil population in Sri Lanka," Singh has said in his reply to Tamil Nadu Chief Minister M. Karunanidhi who wrote to him last month voicing concern about the welfare of Tamils lodged in various camps in the island nation after the end of the war against the LTTE.

Singh said, "We have conveyed these concerns in no uncertain terms to Sri Lanka on various occasions, stressing the need for them to focus on resettling and rehabilitating the displaced Tamil population at the earliest."

India was committed to working on a "priority basis" for the relief and rehabilitation of IDPs in Sri Lanka, Singh said adding "our humanitarian assistance has been substantial."
