Three fighter jets crashed in India's Jammu and Kashmir territory on Wednesday, four local government sources told Reuters, hours after India said it struck nine Pakistani "terrorist infrastructure" sites across the border.

The explosion comes a day after India carried out strikes on nine terror camps within Pakistan and Pakistan-occupied Kashmir.

The neighbors have been in conflict over the disputed border region since their independence and partition in 1947.
