Wasp nest destroyed by some big wasp like insect: is that the queen?
The wasp is a Ropalidia marginata 

The assailant is a greater banded hornet .  
There is a video of one attacking a wasp nest here: https://www.youtube.com/watch?v=BPLRpEkNv8Q

Hornets can attack wasp and bee hives and decimate them. In europe there is an invasive species of hornet from japan which is twice as big as the european hornet. 

The abdomen of the hornet is about half of the size of the animal. The abdomen of the queen Ropalidia marginata is about 1/3rd of the animal, she has very similar markings as the hornet, it seems to have evolved as a copy cat that consumes larvae. http://drkrishi.com/ropalidia-social-wasp/

You must add location information to search for animals by region and find the species. I only knew it was india/pak because of the avatar.
