Benchmark equity indices ended with deep cuts on Thursday, with the Sensex tumbling over 800 points amid a sharp rise in crude oil prices due to the heightening crisis in West Asia.

Besides, sluggish global market trends, weakness in the rupee and persistent foreign capital outflows also rattled investors' sentiment, analysts said.
The 30-share BSE Sensex tanked 829.29 points, or 1.08 per cent, to settle at 76,034.42. During the day, it plunged 992.53 points or 1.29 per cent to 75,871.18.
