Ahead of International Holocaust Remembrance Day on Jan. 27, the World Jewish Congress (WJC) has launched a global campaign encouraging millions of people to use social media to raise awareness about the Holocaust.

The campaign calls on people in every country to hold up a sign with the words “We Remember,” and post it on Facebook, Instagram or Twitter using the hashtag #WeRemember.

Holocaust survivors, lawmakers, government ministers and religious leaders from around the world, as well as soccer and basketball stars, have joined the project and have been photographed holding up “We Remember” signs.

WJC President Ronald Lauder said it is the responsibility of the young generation to teach their friends about the horrors of hatred and spread the message that “never again” means “never again.
