The attack is in response to the upholding of a death sentence handed down to 17-year-old Mohammed al-Nimr.
Naturally, the sentence was appealed but the appeal hearing was held in secret and apparently dismissed.
Here is their upload on YouTube as a warning to Saudi Government.
Currently, most of the sites are back up except for the Ministry of Justices.
Anonymous announced that it began #OpNimr by attacking government websites and taking them offline.
We hope you listen to us this time and release the young man.
You will be treated as a virus and we are the cure.
The hacktivists also criticized the UK for not standing up for Nimr and not doing more to pressure Riyadh.
They also attacked the UN for delegating Saudi Arabia a key human rights role despite the countrys questionable record.
Anonymous spoke directly to King Salman and the Saudi Arabian government in one of their video messages.
We cannot and will not allow this to happen.
Nimr was arrested in 2012, reportedly after participating in a protest.
He was found guilty of joining a criminal group and attacking police officers.
Other charges against him included using a BlackBerry gear to encourage others to come out and join the protest.
The UN has called the trial short of international standards and asked Saudi Arabia to halt the execution.
Reports indicate that Nimr did attend a demonstration, but was not an activist.
This video was posted by Anonymous just after they carried out the task.
