The Sensex, a key Indian stock market index, lost 253 points or 1.84% to close at 13,504 points. The fall was driven by losses in heavyweight companies like Reliance Industries, which fell 4%. Most sectoral indices also ended lower, with energy, power, and capital goods seeing the biggest declines. Foreign investors were net sellers on the day, offloading shares worth $59.6 million. Other Asian and European markets also closed in the red.
