The two women, aged around 80 and 65 years and hailing from Bankati area of Nepal, were found dead soon after a bus carrying over 60 tourists from Nepal and Uttar Pradesh arrived at the bus stand, said Sub-Divisional Police Officer (Puri Dadar), Alekh Chandra Pahi.
The two had come to visit the seaside pilgrim town with their families.
The SDPO quoting their co-passengers said the two women and some other tourists had fallen sick on the way yesterday and complained of vomiting and diarrhoea.
The bodies have been sent for post-mortem and investigation was in progress to ascertain the circumstances that led to the incident.
