I Feel Congress knows every thing about these blasts.If you see the recent incidents in Karnataka 1.Congress thrown Pig Head in Masjid to create problem between Hindu and Muslims and to put balme on BJP.
2.Congress kept some ordinary bombs to tell people that BJP cannot rule.
3.Within 2 hours after blast why congress went to meet Governer?
I am 100% sure now they will do someting to Dr.Ambedkar Statue so that they can blame BJP.
