India's benchmark indexes are poised to open lower on Friday, and the rupee is likely to weaken after the country's defence ministry said that military installations were targeted by drones and missiles originating from Pakistan.

The Indian rupee weakened sharply to log its steepest fall in more than two years on Thursday as the ongoing India-Pakistan conflict hurt the currency alongside the country's bonds and equities.

The rupee opened 14 paise down on May 9 after a night of drone and missile strikes as India and Pakistan conflict worsens. The currency opened at 85.85 against the dollar after ending the previous session at 85.71, its worst day in almost three years.
