The decision came hours after India and the African Union decided to postpone a key economic summit due to the deadly Ebola outbreak in the Democratic Republic of Congo.

Following the postponement of the fourth India-Africa Forum Summit in New Delhi, the big cat gathering will also be rescheduled, India's environment ministry said, adding that African nations are "important partners in global efforts" towards biodiversity protection.

The inaugural big cat summit aimed at protecting the world's seven key big cat species was scheduled to be held on June 1-2.

New dates would be set later, the ministry said.

The big cat summit is set to bring together representatives from nearly 95 countries in Asia, Africa, and the Americas.
