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.

India fired attack drones into Pakistan on Thursday, wounding four soldiers, the Pakistani military said. India, meanwhile, accused its neighbor of attempting its own attack, as tensions soared between the nuclear-armed rivals.

Secretary of State Marco Rubio emphasized the need for “immediate de-escalation” as he spoke with leaders from both countries.
