DMK chief M Karunanidhi described as "mere phrases" President Pranab Mukherjee's mention in his address to Parliament that India was making efforts to resettle and rehabilitate internally displaced people in Sri Lanka.
"Indian government seems not to have understood the unprecedented difficulties and struggles of Eelam Tamils who have lost their livelihood, with it (Centre) trying to dilly- dallying on this issue in the President's address," he said in a statement here.
"These are mere phrases and are not reflective of the grief of Tamils," Karunanidhi said.
He accused Sri Lankan President Mahinda Rajapaksa of pretending to India of being concerned about Tamils' welfare and that whatever assistance he received from New Delhi meant for Tamils was actually being used for Sinhalese, he alleged.
"While many countries are trying to brand him as a war criminal and punish him for the same, one cannot understand why India doesn't understand his designs," he said.
The DMK patriarch also took a dig at his arch rival and Chief Minister Jayalalithaa for condemning the alleged cold- blooded killing of slain LTTE chief V Prabhakaran's son Balachandran, saying she had moved a resolution in the Tamil Nadu Assembly in 2002 seeking the LTTE founder's extradition to India.
