The media is only informing of the exodus from Banglore. There are also passing information that it is happening in South and West India. I googled and while all had Bangalore being the sole area of exodus, this NE paper gives some more details. All one can say instead of the usual nonsense of appealing to stay calm and maintain harmony, it is time to act and catch the culprits and give them an exemplary punishment so that it does not happen again. One commentator (I think he was ex RAW) on a TV debate drew the attention that all places where the exodus is happening is basically where terrorist blasts have occurred earlier.
