Five years after a devastating tsunami left 250,000 dead across Asia, affected countries are marking the grim anniversary with public and private ceremonies and prayers. In Banda Aceh, Indonesia, the site of 150,000 deaths, the country's vice president prayed at a mass grave for tsunami victims with residents of the area, who left flowers as well. The region has been the site of a major international reconstruction effort since the disaster. "[Banda Aceh] is so built up now," a local conservationist told CNN. "Now, we can barely see 100 meters because there's been so much reconstruction. Everything's been built up on both sides of the road."
