Hollywood couple Demi Moore and Ashton Kutcher on Thursday called for a halt on international sex slavery and indentured servitude during the launch of a new UN Trust Fund for Victims of Human Trafficking.

"This is modern day slavery," Moore, who starred in "Ghost" and "GI Jane," said.

Kutcher, having six million Twitter followers, said he wants a trafficking free internet.

Currently an estimated 27 million people are victimized by human trafficking, reports said.

According to Kutcher, about three quarters of the estimated 32 billion dollars in financial exchanges for trafficking in women and children take place on the Internet.

Prostitution is being forced off the streets and "behind the closed doors of the Internet. Behind those closed doors you can make a purchase on the Internet and feel completely anonymous," Kutcher said.

"The truth is slavery globally is a dirty little secret. It is happening everywhere, right in front of our eyes and we ignore it, " he said.

"There are more slaves in the world today than ever before in world history," he said.

"Freedom is a basic human right and slavery is one of the greatest threats to that freedom," Kutcher added.

"No one has the right to enslave another person," Moore said.
