New Delhi, July 12 -- The Indian stock market ended the week with marginal losses, breaking a four-week gaining streak, as rising geopolitical tensions in West Asia and a sharp jump in crude oil prices weighed on investor sentiment.

The week began on a strong note, led by an easing in crude prices, upbeat first-quarter business updates, steady monsoon progress, and broad-based buying interest.

On a weekly basis, the Sensex fell 0.25% to close at 77,569.39, while the Nifty 50 slipped 0.26% to settle at 24,206.90....
