After New Delhi's concerns over the worsening conflict in Sri Lanka and its impact on Tamil civilians, Colombo has decided to send a high-level delegation to India. They will appraise New Delhi of the latest situation," Media Minister Lakshman Yapa Abeywardena told media. Five MPs and two senior officials will visit India following the direction of President Mahinda Rajapaksa.

New Delhi on Thursday summoned Lankan High Commissioner to India C R Jayasinghe and told him that Colombo should address its concerns over the humanitarian situation.

Prime Minister Manmohan Singh and External Affairs Minister Pranab Mukherjee have already asked Colombo to protect the rights of civilians.

On the other hand Sri Lanka has denied of any such happenings. The Sri Lankan Minister said the government knew the difference between the Tamil civilians and the LTTE terrorists.

In a statement, Abeywardena said the government was making all efforts to avoid civilian casualties during its intensified operations against the LTTE in the north.

An estimated 2,30,000 Sri Lankan Tamil civilians have been displaced due to the latest fighting.
