Hopes dimmed on Tuesday in Morocco’s search for survivors, four days after a powerful earthquake killed more than 2,800 people, most of them in remote villages of the High Atlas Mountains. Search-and-rescue teams from the kingdom and from abroad kept digging through the rubble of broken mud-brick homes, hoping for signs of life in a race against time following the 6.8-magnitude quake late Friday. The Red Cross appealed for more than $100 million in aid to meet the “most pressing needs”, including water, shelter, health and sanitation services. Dozens of quake survivors crowded around the open back doors of a truck in Amizmiz waiting for the packages of food aid being handed out by volunteers on Tuesday. Her home in Azmizmiz collapsed in the quake and her children barely managed to escape with their lives.
