Pakistani authorities have arrested 31 Indian fishermen and seized their five vessels for allegedly violating the country's exclusive economic zone in the Arabian Sea, an official said on Sunday.
Maritime Security Agency (MSA) spokesman Lieutenant Commander Shakeel Ahmed Khan told reporters the Indian fishermen were apprehended on Saturday night.
The fishermen would be brought to Karachi harbour for being handed over to local police. Their five boats were also seized.
MSA officials said the fishermen belonged to India's Gujarat state and had set out to sea about six days ago.
India and Pakistan detain dozens of fishermen every year for violating maritime boundaries. Some of the arrested fishermen have languished for months and even years in jails.
In recent months, both countries have taken steps to speed up the release of arrested fishermen.
