(CNN) The United Nations Security Council adopted a resolution Monday that keeps the pressure on suspected human traffickers and sexual abusers in Libya.

The Netherlands spearheaded the effort in the wake of an award-winning undercover report by CNN's Nima Elbagir and Raja Rezak that revealed trafficking of women in Libyan camps, as the observed captives were sold to the highest bidder.

Dutch officials explained that perpetrators of sexual and gender-based violence can now be sanctioned by the UN Security Council. This is a new element in an ongoing Security Council sanctions campaign against Libya.

"The sanctions require countries to freeze the traffickers' assets and impose travel bans on them," The Netherlands' Foreign Minister Stef Blok said in a statement.

"It means that those perpetrators of sexual violence, for instance in the refugee camps who rape women refugees ... it will be possible to sanction them, so we think that's an important step forward, " Karel J. G. van Oosterom, the Netherlands ambassador to the United Nations, told reporters outside Security Council chambers Monday morning.
