India has conducted several large-scale evacuations in modern times, particularly in the Middle East where there is a high concentration of Indians and several conflicts in recent history. The 1990 airlift of Indians from Kuwait has been recognized as the world's largest civilian airlift, with over 110,000 people evacuated. Domestically, Operation Rahat, which the Indian Air Force claimed was the biggest civilian helicopter evacuation ever, airlifted over 19,600 people from Uttarakhand and Himachal Pradesh during the 2013 North India floods.
