New Delhi, June 8 - With families of the two Indians killed in the Nigeria air crash upset over the delay in getting the bodies back, the Indian government Friday said they may have to wait more as it could take some more time to identify the bodies through DNA tests.

"In the case of the two Indian nationals, our understanding is unfortunately that the remains are not in a condition where you can easily identify them," external affairs ministry spokesperson Syed Akbaruddin told reporters here.

"So, they will need (go through) a process of examination, including DNA testing and matching of that test. This is likely to take time, given the facilities there for this sort of a thing," he said.

Mahendra Singh Rathore, the co-pilot, and Rijo K. Eldhose, a young computer engineer from Kerala, were among the 153 people who perished when the Dana Airlines plane crashed in Lagos Sunday.

The Indian mission in Lagos has been in touch with the governor of Lagos over the identification of bodies of the two Indians.
