Survivors of Morocco's deadliest earthquake in more than six decades struggled to find food, water and shelter on Sunday as the search for the missing continued in remote villages and the death toll of more than 2,100 seemed likely to rise further.

Many people were spending a third night in the open after the 6.8 magnitude quake hit late Friday. Relief workers face the challenge of reaching the worst-affected villages in the High Atlas, a rugged mountain range where settlements are often remote and where many houses crumbled.

The death toll climbed to 2,122 with 2,421 people injured, state TV reported. Morocco said it may accept relief offers from other countries and will work to coordinate them if needed, according to state TV.
