India says its strikes into Pakistan-administered Kashmir and Pakistan on Wednesday killed more than 100 militants.

Residents and officials in the disputed Kashmir region say there was overnight border fighting between Pakistani and Indian troops, despite a ceasefire to stop a conflict between the two countries.

The ceasefire has halted what some analysts say was the most serious fighting between the two countries since a 1971 war. But India's recent suspension of a key water-sharing treaty remains in place.
