At least three Christian prayer halls have been vandalised and preachers allegedly abused, threatened and beaten up in Tamil Nadu's Madurai district since Sunday. Christian groups say a prayer hall called Vaanathin Vaasal (Gates to Sky) at Madurai's Sikkander Savadi was attacked at 9 am on Sunday when the prayer meeting was on. Pastor Ravi Jacob, 41, said, "A group of around 30 people led by one Thangam Venkatesh ransacked the prayer hall. They also burnt our bibles and song books, destroyed our musical instruments and other items."
