Rescuers were working Tuesday to reach small mountain towns in Morocco close to the epicenter of Friday's earthquake, as the military began erecting field hospitals and attempting to provide aid with helicopters.
Government officials said at least 2,901 people have died, with 5,530 injured in the magnitude 6.8 tremblor.
Aid organizations said the catastrophe has left up to 300,000 people in need -- a huge challenge for relief efforts.
Search teams from Britain, Spain and Qatar joined the Moroccan military in an increasingly desperate effort to find and free any survivors trapped in the rubble of collapsed buildings.
Impassable roads and heavy damage were impairing efforts, said Moulay Hafid Alaouie, head of Morocco's Red Cross in Marrakech-Safi.
