Sri Lanka has freed 126 fishermen from Tamil Nadu it arrested over the last few month.

Some of the released fishermen arrived in India on Friday, however their boats remained in Sri Lanka's custody.

The Rameswaram fishermen who had been languishing in Anurathapuram prison complained about inhumane treatment while they were in prison, including being given rotten food.

At least one fisherman said he suffered from food poisoning and was treated in the jail hospital, according to The Hindu.

Earlier this year, Sri Lankan Prime Minister Ranil Wickremesinghe repeatedly stated the Sri Lankan navy had the right to shoot Indian fishermen who stray into its waters.
