Benchmark stock indices ended lower on Monday, with both BSE Sensex and Nifty 50 falling nearly 1 per cent. The decline came after the failure of US-Iran negotiations raised fears of prolonged conflict and a sharp rise in crude oil prices, reported PTI.

The Sensex fell 702.68 points (0.91 per cent) to close at 76,847.57. During the day, it dropped as much as 1,681.93 points before recovering some losses. The Nifty slipped 207.95 points (0.86 per cent) to end at 23,842.65.
