On the WTA side, the Kolkata and Bangalore events have been cancelled. Sisters Neha and Shikha Uberoi expressed that this was due to bad management rather than the recent Mumbai terrorist attacks:
The sisters also expressed their concerns about a couple of high-profile WTA tour events being cancelled in India. "The cancellation of the Sunfeast Open and the Bangalore Open had nothing to do with the terror attacks. It was all due to bad management," said Shikha. "We would like to have at least one WTA Tour event in India, but how do we ask?
I can't find any articles on the cancellation of these two Challengers, but I am guessing the motives might be the same.
