Visakhapatnam, Oct 9 (ANI): Around twenty trains were cancelled as the announcement of the bifurcation of Andhra Pradesh evoked violent protests, forcing the authorities to clamp a curfew in the region. Deepening the crisis, the Electricity department employees stalled work, plunging large parts of the region into darkness. As a result of the power crisis, many trains have been cancelled. A fresh round of talks failed on Wednesday between Andhra Pradesh Chief Minister Kiran Kumar Reddy and the striking power sector employees, who are reportedly not stepping back. Political analysts have observed that the move to bifurcate Andhra Pradesh, by the center ruling Congress was to shore up its political fortunes.
