Amritsar, Apr 19 (ANI): Dalbir Kaur, sister of Sarabjit Singh who was convicted of terrorism and spying by a Pakistani court, said she was reminded of her brother Sarabjeet when she got to know that Kirpal Singh's body was coming today. Kaur said she was sure that Kirpal Singh died an unnatural death and that too under suspicious circumstances. She alleged that Indian prisoners were mistreated in Lahore prisons. Kaur added that she came to know from various sources that life of Indian prisoners was in grave danger, especially Kuldeep Kumar from Ahmedabad and Ansari from Maharashtra. She said that she would appeal to External Affairs Minister Sushma Swaraj to take cognizance of the situation and hence save the lives of the jailed Indian prisoners.
