Forty children's homes and orphanages have closed in Uganda in the past week after the government ordered all unregistered facilities to shut down.

In all, more than 500 homes will be affected and it's unclear what will happen to the children they look after.

The government accuses some orphanages of involvement in child-trafficking and dubious adoption practices.

But other care home managers argue that, whether certified or not, they have stepped in where the government has failed, rescuing street children and saving others who were severely malnourished.

Just 70 homes have been cleared to continue operating, along with the single government-run reception centre.
