What has happened is typical nationalistic approach to bhai chara across the border! May I add, there is slight exaggeration in the title, he is a bit comedian in Pakistan and hardly famous. Comedy Circus might have made him famous In Hindustan (that's a different matter).
he is a very well known stage artist :) ...who also had worked in several TV dramas and Pakistani movies.
if you are not aware of him that doesn't mean he is not famous.
