Libyan authorities have launched an investigation into the collapse of two dams that caused a devastating flood in the coastal city of Derna, resulting in over 11,000 deaths and 10,000 people still missing. Search teams are combing through the streets, wrecked buildings, and even the sea to look for bodies, while the Libyan government has declared a state of emergency in the region and is providing aid. The investigation into the cause of the collapse of the two dams is ongoing.
