Sliding for the sixth straight session, equity benchmark Sensex on Thursday plunged about 900 points to crash below the 64,000 level due to an across-the-board selloff amid heightened tension in the Middle East.
Besides sluggish trends in global markets, deep losses in auto, financial and energy stocks as well as fresh selling by foreign investors added to the gloom, analysts said.
