In April 2015, Indian Armed Forces launched a humanitarian rescue operation called Operation Raahat to evacuate its citizens from Yemen on a war-footing.
The rescue operation was probably one of the toughest for India and probabaly one of the most stellar rescue missions ever conducted in a strife-torn area internationally, since there were many stakeholders in the war: Shia Houthi rebels, Al-Qaeda, Yemen, Saudi Arabia. In such a scenario it could be extremely difficult and confusing for rescue any team since no one know who the enemy really is.

The Operation Rahat has impressed The Royal Navy of the United Kingdom so much that it wants to study it, officially.
In a short span of 10 days, Indian Armed Forced rescued over 5,600 people including 960 foreign nationals from 41 countries.

“The operation was phenomenally successful. India also rescued our citizens from Yemen. The evacuations were done in record time. This is so inspiring that we now want to get associated with the Indian Navy to engage in combined humanitarian relief work,” Captain Stuart Borland, naval and air adviser to the Royal Navy, told The Sunday Guardian.
