New Delhi, Sep 11 (ANI): Union Telecom Minister, Kapil Sibal, called the religious riots in Muzaffarnagar that killed at least 32 people and forced hundreds to flee their homes, as a shameful act and a sign of rising tension between Hindus and Muslims ahead of 2014 general election. Earlier in the day, curfew relaxation for four hours by the authorities brought some respite to the residents of the violence-hit area.
