A 7.7 magnitude earthquake rattled much of Southeast Asia on Friday, flattening skyscrapers and leaving more than 1,000 people dead from Myanmar to Thailand.

BANGKOK (AP) — The death toll from the earthquake that hit Myanmar nearly a week ago rose Thursday to 3,145 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.
