Union Minister Kiren Rijiju today said he was not aware of rape threats to Delhi University student Gurmehar Kaur when he posted a tweet criticizing her post. Mr Rijiju also said he stood by his view that the 20-year-old is being used as a "pawn". On Tuesday, Mr Rijiju drew sharp reactions when he tweeted, "Who's polluting this young girl's mind? A strong Arm Force prevents a war. India never attacked anyone but a weak India was always invaded."
