Hundreds of people have died after a mudslide near to the capital city of Sierra Leone.
Sierra Leone is a country in West Africa.
Last week a hill near Freetown collapsed after heavy rain, burying many houses.
So far, almost 400 people have lost their lives and at least 600 more are still missing.
There has also been a lot of flooding, which has swept many more homes away. Many have been left homeless after their houses were destroyed in the tragedy.
Sierra Leone’s president said the country would need “urgent support” to recover from what has happened.
The emergency services are working very hard to try to find people who are still missing. But because of the floods and the damage, it is hard to get equipment and helpers to where they are needed.
