Chennai, Mar 12 (UNI) The ruling DMK in Tamil Nadu today staged an hour-long demonstration to condemn the indiscriminate killing of Tamil fishermen and demanded an end to this undeclared war by the Lankan navy, even as fishermen in Rameswaram stayed away from sea to condemn the attacks.

The hour-long demonstration, held in front of the office of the Sri Lankan Deputy High Commission here, was led by Tamil Nadu Fisheries Minister K P P Samy and more than 5,000 DMK activists participated in it.

Tamil Nadu Ministers Arcot N Veerasamy, K Duraimurugan, M K Stalin, Parithi Elamvazhuthi and T M Anbarasan and party functionaries J Anbazhagan and L Balaraman, were among those, who participated in the agitation.

Later, Mr Samy accompanied by Mr Veerasamy and Mr Stalin submitted a memorandum to Sri Lankan Deputy High Commissioner P H Amza, urging him to take immediate steps to put an end to the ''undeclared war'' indulged in by that country's navy against the unarmed and innocent fishermen of Tamil Nadu.

In the memorandum, the DMK said the Lankan Navy had indulged in unprovoked attacks on Tamil Nadu fishermen. ''They had shot fishermen to death. Fishing boats and catches of fishermen were unlawfully seized and a few fishermen were illegally arrested.'' More UNI
