Sorry, anonymous sources cannot be considered credible.
Even if there are RAW personnel in Afghanistan, it is a matter between India and Afghanistan, because Afghanistan is a sovereign independent country. Furthermore, even if Indians are talking with Sindhis or Punjabis or Balochis or Pakhtuns, there is nothing wrong with it. If Pakistanis allege there was any contravention of international law, they should provide evidence.
Dude, the evidence has been provided to Afghan and US governments. They continue to let indians export terrorism because of their interests and thus we have to use other ways to contain or stop indian terrorism.
The amount of indian intelligence present in Afghanistan should itself be a red flag anyhow.
