Badawi co-founded the Liberal Saudi Network website in 2008 as a forum to discuss religion and in 2012, he was arrested on charges of insulting Islam through his blog and in television comments. He was sentenced in 2013 to seven years in prison and 600 lashes, a verdict he appealed. A retrial was ultimately ordered.
Badawi's wife, Ensaf Haider, asked, "How is it possible they could take a sentence that was already so hash and make it even harsher? Ten years in jail and 1,000 lashes? That's unimaginable. I'm extremely scared for my husband."
Amnesty International denounced Wednesday's court ruling, describing Badawi as a "prisoner of conscience" who must be released.
"Raif Badawi is the latest victim to fall prey to the ruthless campaign to silence peaceful activists in Saudi Arabia."
