B ANGKOK — The death toll from the massive earthquake that hit Myanmar nearly a week ago rose Thursday to 3,085 as search and rescue teams found more bodies, the military-led government said, and humanitarian aid groups scrambled to provide survivors medical care and shelter.

The death toll from Myanmar's devastating earthquake has surpassed 3,000, with hundreds more missing, as forecasts of unseasonal rain presented a new challenge for rescue and aid workers trying to reach people in a country riven by civil war.

The surprise announcement by the unelected government said the halt in fighting would run until April 22 to show compassion for people affected by last week's quake.
