Although we don't have a lot of information on this, it is known that RAW was also involved in the Anti-Apartheid movement in South Africa and Namibia. They were even responsible for training intelligence officers of a number of independent countries of the African continent. Many retired RAW officers worked in the training institutes of these intelligence agencies as well.
RAW has been involved in snatch operations for quite some time now. A snatch operation is when RAW officers catch the suspect in a foreign country and get them into the country for interrogation in undisclosed locations. This is generally done to bypass a lengthy extradition process. A good example of a snatch operation would be Akshay Kumar's film BABY.
In the last decade, RAW has carried out close to 400 successful snatch operations in Nepal, Bangladesh and other countries.
Some famous terrorists nabbed are Bhupinder Singh Bhuda of the Khalistan Commando Force, Lashkar militants Tariq Mehmood and Abdul Karim Tunda, Sheikh Abdul Khwaja, one of the handlers of the 2008 Mumbai attacks, Yasin Bhatkal founder leader of the proscribed terrorist organisation Indian Mujahideen among others.
These were only a few operations that have been declassified. There are countless others which you don't get to hear about, probably never will either. What we do know is that we are in safe hands.
