Continuing a 31-year practice, India and Pakistan on Saturday exchanged a list of their nuclear installations under a bilateral pact that prohibits the two sides from attacking each other's atomic facilities.

The two countries exchanged the list of nuclear installations and facilities covered under the agreement on the prohibition of attack against nuclear installations between India and Pakistan, the Ministry of External Affairs (MEA) said.

This was done simultaneously through diplomatic channels in New Delhi and Islamabad.

The pact that came into force in 1991 provides for the two countries to inform each other of the nuclear installations and facilities covered under the agreement on the first of January of every year.

"India and Pakistan today exchanged, through diplomatic channels simultaneously at New Delhi and Islamabad, the list of nuclear installations and facilities, covered under the agreement on the prohibition of attack against nuclear installations and facilities between India and Pakistan," the MEA said in a statement.

The exchange of the list came amid strain in ties between the two countries over the Kashmir issue as well as cross-border terrorism.

"The agreement, which was signed on December 31, 1988, and entered into force on January 27, 1991, provides, inter alia, that India and Pakistan inform each other of the nuclear installations and facilities to be covered under the agreement on the first of January of every calendar year," the MEA said.

"This is the 31st consecutive exchange of such lists between the two countries, the first one having taken place on January 1, 1992," it said.

Repatriate 356 fishermen: India to Pakistan

India on Saturday called on Pakistan to release and repatriate 356 Indian fishermen and two civilian prisoners whose nationality has already been confirmed and conveyed to Pakistani authorities.

In addition, Pakistan has been asked to provide immediate consular access to 182 Indian fishermen and 17 civilian prisoners who are in Pakistan's custody and are believed to be Indian, the Ministry of External Affairs (MEA) said.

India made the request in the context of the exchange of the lists of civilian prisoners and fishermen by both the countries as part of a practice to do so on January 1 and July 1 of every calendar year under the framework of a 2008 agreement.

The MEA said India handed over a list of 282 Pakistan civilian prisoners and 73 fishermen in India's custody to Pakistan. Similarly, Pakistan has shared lists of 51 civilian prisoners and 577 fishermen in its custody, who are Indians or are believed to be Indians.

It said India has called for early release and repatriation of civilian prisoners, missing Indian defence personnel and fishermen, along with their boats, by Pakistan.

"In this context, Pakistan was asked to expedite the release and repatriation of two Indian civilian prisoners and 356 Indian fishermen to India whose nationality has been confirmed and conveyed to Pakistan," the MEA said in a statement.

In addition, it said, Pakistan has been asked to provide immediate consular access to 182 Indian fishermen and 17 civilian prisoners who are in Pakistan's custody and are believed to be Indians.

"The government also requested Pakistan to expedite the grant of visas to the members of the medical experts' team and facilitate their visit to Pakistan to assess the mental condition of believed-to-be Indian prisoners of unsound mind, lodged in different jails of Pakistan," the MEA said.

"It was also proposed to organise an early visit of the Joint Judicial Committee to Pakistan," it said.

The MEA said India remained committed to addressing, on priority, all humanitarian matters, including those pertaining to prisoners and fishermen in each other's country.

"In this context, India has also urged Pakistan to expedite necessary action at its end to confirm the nationality status of 68 Pakistan prisoners, including fishermen, whose repatriation is pending for want of nationality confirmation by Pakistan," the MEA said.

"In view of the Covid -19 pandemic, Pakistan has been requested to ensure the safety, security and welfare of all Indian and believed-to-be Indian civil prisoners and fishermen," it said.
