The number of people who have died in Morocco following the earthquake has now hit 1,037, state television quotes the interior ministry as saying.
The quake – measuring magnitude 6.8 – sent people rushing into the streets in Marrakesh and other cities.
Many of the deaths were said to be in hard-to-reach mountain areas.
The quake struck just after 23:00 local time, at a relatively shallow depth of 71km (44 miles) south-west of Marrakesh, according to the US Geological Survey.
Dramatic video footage show damaged buildings and rubble-strewn streets.
Meanwhile a UK search-and-rescue charity is standing by to send a team to Morocco.
Mark Scorer, director of operations at Saraid, told the BBC they are ready to help if needed – as they did earlier this year following the devastating Turkey earthquake.
Scorer said rescuers could begin providing expert advice and assistance within 12 to 24 hours.
