Domestic equity benchmark indices Sensex and Nifty ended lower on Thursday, extending their losses for fourth straight session as the soaring crude oil prices amid the escalating tensions in West Asia continued to weaken investor sentiment.

The 30-share BSE Sensex lost 363.66 points, or 0.47 per cent, to end at 76,391.39, while the 50-share NSE Nifty slid 126.65 points, or 0.53 per cent, to settle at 23,869.60.
