A magnitude 3.9 aftershock shook Moroccans on Sunday even as rescuers worked to find survivors in the mounds of rubble left in villages from the powerful earthquake that struck Friday night, killing more than 2,100 people.
The United Nations estimated that 300,000 people were affected by the magnitude 6.8 quake, the country's most powerful in a century. Rescue efforts were slow, and some Moroccans complained on social networks that the government wasn't allowing more rescue workers into the country to help.
