The victims -- Nirpreet Kaur, Jagdish Kaur -- and others were on an indefinite fast for the past six days against the acquittal of Congress leader Sajjan Kumar in a 1984 riots case.
Protesters said the health of the fasting persons deteriorated and the top religious heads adviced them to call off their strike.
A court here on April 30 acquitted Kumar in a 1984 anti-Sikh riot case in which he was accused of murder and of instigating a riotous mob that killed five Sikhs in Delhi's cantonment area.
