By Aftab Ahmed, Adnan Abidi and Saeed Shah JAMMU, India/ISLAMABAD (Reuters) - Blasts rang out across the city of Jammu in Indian Kashmir late on Thursday during what India's military said was a Pakistani drone and missile attack across the disputed region on the second day of clashes between the nuclear-armed neighbours.

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

Tension between the nuclear-armed nations is soaring. Pakistan's Shehbaz Sharif has vowed to retaliate after Indian strikes killed more than two dozen people.
