Benchmark equity indices Sensex and Nifty plunged more than 1 per cent on Monday, falling for the fourth day running, amid weak trends in global markets in view of heightened tensions in the Middle East. Crude oil quoting above USD 90 a barrel mark also played spoilsport for the markets. The 30-share BSE Sensex plunged 825.74 points or 1.26 per cent to settle at 64,571.88. During the day, it plummeted 894.94 points or 1.36 per cent to 64,502.68. The Nifty fell 260.90 points or 1.34 per cent to 19,281.75.
