India and Pakistan on Saturday reached an understanding to stop all military actions on land, in the air and at the sea, in a U.S.-brokered ceasefire.

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.

Pakistani officials have said Saturday’s ceasefire with India reestablished deterrence. But New Delhi insists the rules of engagement have irrevocably changed.
