Myanmar's state-run television says the death toll in the powerful earthquake that struck central parts of the country on Friday has climbed to 1,644.



The US Geological Survey says the magnitude 7.7 quake occurred near the city of Mandalay at an estimated depth of about 10 kilometers.



Another jolt with a magnitude of 6.7 followed about 10 minutes after the initial tremor.



In neighboring Thailand, authorities say at least five people are dead and 17 others injured after the shaking brought down a high-rise building that was under construction in the capital, Bangkok.



Rescuers are searching for about 100 people believed to be trapped in the rubble.



Thai Deputy Prime Minister Anutin Charnvirakul visited the site on Friday night. He said both public and private buildings will be required to undergo safety inspections.
