CNN’s Will Ripley reports from Bangkok the day after a 7.7 magnitude quake hit the region. Myanmar’s ruling military said Saturday on state television that the confirmed death toll from a devastating 7.7 magnitude earthquake rose to 1,644, as more bodies were pulled from the rubble of the scores of buildings that collapsed when it struck near the country’s second-largest city. The new total is a sharp rise compared to the 1,002 total announced just hours earlier, underlining the difficulty of confirming casualties over a widespread region and the likelihood that the numbers will continue to grow from Friday's quake. The number of injured increased to 3,408, while the missing figure rose to 139. Rescue efforts are underway especially in the major stricken cities of Mandalay, the country's No. 2 city, and Naypyitaw, the capital. But even though teams and equipment have been flown in from other nations, they are hindered by the airports in those cities being damaged and apparently unfit to land planes. Myanmar, also known as Burma, is in the throes of a prolonged civil war, which is already responsible for a humanitarian crisis. It makes movement around the country both difficult and dangerous, complicating relief efforts and raising fears that the death toll could still rise precipitously. The earthquake struck midday Friday with an epicenter not far from Mandalay, followed by several aftershocks, including one measuring 6.4. It sent buildings in many areas toppling to the ground, buckled roads, caused bridges to collapse and burst a dam. In Naypyidaw, crews worked Saturday to repair damaged roads, while electricity, phone and internet services remained down for most of the city. The earthquake brought down many buildings, including multiple units that housed government civil servants, but that section of the city was blocked off by authorities on Saturday.
