May 21 (Reuters) - Indian shares ended lower for a fifth straight session on Monday, with the NSE index closing at its lowest level in more than a month, as political turmoil in the southern state of Karnataka unnerved investors.
The broader NSE index closed 0.75 percent lower at 10,516.70, while the benchmark BSE index fell 0.67 percent to 34,616.13.
The BSE index closed at its lowest level since April 25.
Financials were among the biggest drag on both indexes, with Housing Development Finance Corp ending 1.8 percent lower.
Pharma companies Sun Pharmaceutical Industries Ltd and Dr. Reddy’s Laboratories Ltd were among the biggest losers, both closing over 4 percent lower.
