India and Pakistan exchanged lists of the two countries' nuclear facilities and lists of citizens imprisoned in the neighboring country on Saturday, the Ministry of Foreign Affairs of India said on the official website.

The exchange of the list of nuclear facilities took place in accordance with the 1988 treaty to prevent attacks on such facilities.

India and Pakistan exchanged today through diplomatic channels simultaneously in Delhi and Islamabad the list of nuclear installations covered by the Agreement on the Prohibition of Attacks on Nuclear Installations between India and Pakistan, the Foreign Ministry said.

The treaty stipulates that the two neighboring nuclear powers of South Asia at the beginning of each year notify each other about nuclear facilities on their territory in order to prevent unauthorized attacks on them. This measure is considered one of the most important in maintaining security in the region. The first exchange of such documents took place on January 1, 1992.

The two countries also gave each other lists of citizens of the other side who are in prisons on their territory.

The Indian diplomatic service noted that the exchange took place through diplomatic channels in accordance with an agreement of 2008, according to which the transfer of such lists is carried out twice a year - on January 1 and July 1.

India has handed over to Pakistan the lists [of] 282 Pakistani civilians and 73 fishermen imprisoned in India. Likewise, Pakistan has shared lists [of] 51 detained civilians and 577 fishermen who are Indian or may be Indian, the Foreign Ministry said.

Citizens of India and Pakistan often find themselves on the adjacent side due to the inaccurately demarcated border in the mountainous regions. There are always many fishermen among the prisoners. The Coast Guard of both India and Pakistan regularly detain them for infiltrating adjacent territorial waters. One of the main reasons for this is the uncertainty of the maritime borders between countries in the Arabian Sea, in addition, fishing boats often do not have equipment that allows them to accurately determine their location. At the same time, Islamabad and New Delhi periodically release the detained citizens of the neighboring country.
