The smell of decaying bodies permeated the streets of Myanmar's second-largest city on Sunday as people worked frantically by hand to clear rubble in the hope of finding someone still alive, two days after a massive earthquake struck that killed more than 1,600 people and left countless others buried. The 7.7 magnitude quake hit midday Friday with an epicenter near Mandalay, bringing down scores of buildings and damaging other infrastructure like the city’s airport. Relief efforts have been hampered by buckled roads, downed bridges, spotty communications and the challenges of operating in a country in the midst of a civil war.
