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.

On Thursday, the local legal tender had dropped sharply by 89 paise to close at 85.72 after clocking a 19 paise stronger open at 84.64.
