Bulk deletion of computer and user accounts in Active Directory not working

Looking to delete computer accounts and user accounts in Active Directory

Got below script for computer accounts previously

Import-Csv -Path C:\Temp\DisableComputer.csv | ForEach-Object {Remove-ADComputer -Identity $_.Name -WhatIf}

It ran fine above then I changed it to below to run it properly

Import-Csv -Path C:\Temp\DisableComputer.csv | ForEach-Object {Remove-ADComputer -Identity $_.Name}

Problem is it doesnt perform deletion of computer accounts in a batch, have to do it one by one and see below error

Remove-ADComputer : The directory service can perform the requested operation only on a leaf object

Looking for a way to bulk delete and also modification required to bulk delete AD user accounts also
