The Sun said comments were made on the forum of Ummah.com.
A post on the forum apparently called for users to compile "a list of top Jews we can target," which included both Winehouse and Ronson's names.
British anti-terror expert Glen Jenvey told The Sun that the comments should be taken seriously.
"The Ummah website has been used by extremists," he said. "Those listed should treat it very seriously. Expect a hate campaign and intimidation by 20 or 30 thugs."
Other celebrity's allegedly included on the list are The Apprentice U.K.'s Sir Alan Sugar and British Foreign Secretary David Miliband.
Protesting in Trafalgar Square yesterday (January 6), U2/Coldplay producer and former Roxy Music star Brian Eno made a speech about the conflict.
Eno showed his support for Palestine, and urged people to get in touch with government officials to call for an end to the troubles.
