Hamad Awad sat on a blanket on an empty street with a bottle of water and bedding alongside him. "I am staying in our area trying to clean it and trying to verify who is missing," he said. Entire districts of Derna, with an estimated population of at least 120,000, were swept away or buried in brown mud. It cited the Libyan Red Crescent for the figure but a Libyan Red Crescent spokesman said it had not published a toll and referred Reuters to government spokespeople, saying "figures are changing and the Red Crescent is not responsible for this." Civil protection workers from Algeria combed through the rubble of multistorey buildings with a dog to help detect any survivors.
