Pakistan has ordered the release on humanitarian grounds of 100 Indian fishermen, most of them from Gujarat, languishing in prison for “illegally venturing” into its territorial waters, the Pakistani prime minister’s office said.

“As a humanitarian gesture, Prime Minister Yusuf Raza Gilani has decided to unilaterally release 100 Indian fishermen who have been in Pakistani custody,” the prime minister’s office said in a statement released late on Tuesday.

A prison official in the port city of Karachi, where the fishermen are being kept, said nine children were among the group of 100 to be released.

“We have made arrangements to release 100 fishermen, as directed by the government, out of the 618 currently being held in Karachi jails,” said Shahab Siddiqui, assistant superintendent of Karachi’s Malir prison.

They would be repatriated on Thursday, Gilani’s office said.

Pakistan had also proposed the revival of a joint judicial committee to resolve the issue of prisoners and fishermen in each other’s custody, the office said.

Relations between the nuclear-armed rivals have been strained since an assault in the Indian city of Mumbai in November last year by Pakistani-based militants.

A peace process has been in suspended motion, and there has been no progress towards getting it resumed. Analysts say another militant strike in India could risk bringing the neighbors to the brink of conflict.

The two countries frequently arrest each other’s fishermen for encroachment and often release them as a show of goodwill.

There are about 500 Gujarat fishermen languishing in Pakistan jail. Many of them have completed their prison period. Earlier Pakistan used to free seized boats along with the arrested fishermen, but for last two years only fishermen are released. Pakistan has about 433 Gujarat boats worth crores of Rs.
