Dhaka - Bangladesh on Saturday accused Pakistan of breaching the post-1971 war agreement by not taking back thousands of its stranded citizens, affecting the validity of the treaty.

"Under the 1974 agreement (among Dhaka, New Delhi and Islamabad), Pakistan was obligated to take back its stranded citizens from Bangladesh. They did not fulfil their obligation over the decades," Bangladeshi Law Minister Anisul Huq said at a discussion in Dhaka.

He said, Bangladesh on the other hand, complied with the treaty allowing the defeated Pakistani soldiers' repatriation and in no way breached the agreement by bringing to justice Bangladeshi perpetrators of war crimes who carried out atrocities siding with the Pakistani troops.

He added that according to the principle of law, if any party violates a treaty, its validity comes into question while Pakistan itself "clearly defied" the agreement by refusing to take back its citizens over the decades.

The law minister's comments came amid a growing diplomatic row between the two countries as Pakistan recently accused Bangladesh of failure to uphold the commitment of "not to proceed with the trials" in line with the 1974 treaty.
