The four Indians - two auditors, a consultant for Afghan government projects and an NGO worker- were among 14 people killed in the attack by the militants who stormed the Park Palace Guesthouse on Wednesday.
Among the others who were killed in the five-hour assault were two Pakistanis, an Italian, his Kazakh wife and a US national.
According to a top Afghan government official, the Indian Ambassador to Afghanistan could have been the target of the Taliban attack, a view which was echoed by the envoy of that country here.
