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 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.

India launched strikes on Pakistan after a deadly terror attack in Kashmir, a territory that it has long fought over with Pakistan.
