Snapping two-day gaining streak, Indian equity benchmark -- Nifty ended lower on Tuesday amid renewed US-Iran Jitters. Index made a flat-to-negative start following mixed cues from other Asian markets. However, soon the market added some gains and traded marginally in green terrain as some support came with renewed foreign fund inflow. According to exchange data, foreign institutional investors bought equities worth Rs 821.75 on May 25. In afternoon session, market, however, witnessed sharp sell-off amid renewed uncertainty over US-Iran peace deal as US attacked key Iranian missile launch sites in Southern Iran and boats attempting to lay mines. Further, market participants opted to book profit at higher levels and avoided risky bids ahead of weekly nifty expiry. In last leg of the session, index extended losses and ended near 23,900 mark.
