The neighbors had agreed to a full and immediate cease-fire in the worst violence between them for more than two decades.

India and Pakistan agreed to an immediate ceasefire on Saturday, unexpectedly halting the worst fighting in decades between the nuclear-armed neighbors, just when their tit-for-tat strikes appeared to be spiraling out of control.

Blasts were heard in Srinagar and Jammu and projectiles and flashes were seen in the night sky over Jammu, similar to the events of the previous evening, according to authorities, residents and Reuters witnesses.
