Indore: Enraged by Pakistani-origin Canadian writer Tarek Fatah's critical remarks about their country, two Pakistani writers today walked out of the inaugural session of the Indore Literary Festival here.

"Islamic extremism is a problem. If you (writers) have to deal with it, then learn to speak the truth. If you don't have the courage to speak it, then better sit at your home and sell onions and tomatoes," Fatah said addressing the session on 'Religious Extremism and Contemporary Times'.
