The benchmark BSE Sensex fell over 350 points in early trade on Tuesday amid rising tension between India and Pakistan, weak Asian cues and selling pressure on banking, power, IT and power counters.
The Sensex was trading 343.20 points, or 0.95 per cent, down at 35,870.18 after touching a low of 35,842.58. The gauge rallied 342 points in Monday's trade.
The 50-share Nifty also fell 105.45 points, or 0.97 per cent, to 10,774.65.
According to brokers, domestic investor sentiment took a beating after the Pakistan Army on Tuesday alleged that the Indian Air Force violated the Line of Control (LoC) in Muzafarabad sector.
The allegation came amid heightened tension between India and Pakistan after the February 14 suicide attack by Pakistan-based Jaish-e-Mohammad terror group that killed 40 CRPF soldiers in Jammu and Kashmir's Pulwama district.
