Note:

Only empty buckets can be deleted. If there are still objects or incomplete multipart uploads in a bucket, its deletion will fail. Make sure that there are no objects in the bucket before deleting it.

Before deleting a bucket, make sure that the current identity has been granted the permission to delete it and that the correct Bucket and Region parameters are passed in.
