July 23 (Reuters) - Indian equities opened lower on Thursday, as oil prices climbed past $95 a barrel after the U.S. launched fresh strikes on Iran and Yemen's Houthis targeted oil tankers in the Red Sea, hurting global risk appetite.
Higher oil prices pose a key risk for India, the world's third-largest crude importer and consumer, by stoking inflation, widening the trade gap, squeezing growth and corporate margins.
A 4% drop in drug maker Dr Reddy's Laboratories and a 5% drop in oil marketing company HPCL on weak quarterly results also weighed on markets.
The benchmark Nifty 50 fell 0.22% to 23,944.45, while the BSE Sensex shed 0.27% to 76,544.26.87 by 9:23 a.m. IST, both on course for fourth straight session of losses.
Thirteen of the 16 major sectors logged losses at the open. The broader small-caps and mid-caps fell 0.3% each.
