New Delhi, Jan 2 (PTI): India and Pakistan on Friday exchanged a list of their nuclear installations under a bilateral agreement that bars them from attacking each other's atomic facilities.

The two countries also exchanged, through diplomatic channels simultaneously at New Delhi and Islamabad, the lists of nationals (including civil prisoners and fishermen) of each country lodged in their respective jails.

The agreement pertaining to nuclear installations which was signed on December 31, 1988 and entered into force on January 27, 1991 entails that the two countries should inform each other of nuclear installations and facilities to be covered under the Agreement on January 1 every year.

The agreement on prisoners, which was signed on May 31, 2008, provides that a comprehensive list of nationals of each country lodged in other country's jails has to be exchanged twice each year, on January 1 and July 1 while the list of nuclear installations is exchanged only on January 1.
