Tourists and VFR travelers trying to get rid of their Indian cash at Indian airports by exchanging it into non-Indian currency have been having problems last night/today. Something about maximum exchange into foreign currency being restricted to 5000 INR in total.

This move is burning a lot of travelers too, not to ignore the suicide(s) it has resulted in too. In terms of who is responsible for the situation? The PM said he had no choice but to make this a secret scheme and make the decision himself on doing this.

It's quite ordinary for foreign tourists departing India to have more than 5000 INR on arrival at the Indian airport of exit, and then they may try to exchange back the INR for foreign currency at the airport. But the Indian government has just "taxed" them with this move too, and the chances of visitors having to abandon the cash and/or cash's value has increased substantially.
