Strongly reacting to the killing of a second Indian fisherman in less than a fortnight allegedly by the Sri Lankan Navy, New Delhi on Sunday termed it as "unacceptable" and sought a report in the matter from its mission in Colombo.
External Affairs Minister SM Krishna has taken the matter "very seriously", saying it is "unacceptable" and has sought a report from the Indian mission.
The Minister's office has also asked Tamil Nadu Special Department to provide the details regarding the fisherman and the incident.
The fisherman was killed and two others were injured while fishing off Kodiakarai coast yesterday.
The man, who had put out to sea with two others from Pushpavanam coastal hamlet, died after Sri Lankan Naval personnel allegedly tied a rope around his neck and pushed him into the water, fisheries department sources said.
On January 12, in an incident of attack on Tamil Nadu fishermen in Palk Straits, one person was killed when Lankan Navy allegedly opened fire at three fishermen, who put out to sea from Jagadapattinnam near Pudukottai.
