More than 170 children are still feared missing and UNICEF officials said they were organising transit centers to help unaccompanied children in the wake of the disaster.
At least 37 people have died and 18 others are seriously injured after the accident in Cameroon’s western village of Nemale.
With no work and little public transport during a lockdown, many urban migrants attempting to return to their home villages have set out on gruelling journeys on foot or hitching rides in the back of trucks.
Local media said the man arrested had claimed responsibility for the attack. At least four people died when the truck was driven into a department store in central Stockholm.
