Germany marked the 80th anniversary of the liberation of the Buchenwald concentration camp, with former president Christian Wulff warning of radicalization and a global shift to the right. Wulff called for active commitment to democracy and criticized the far-right Alternative for Germany party. Holocaust survivor Naftali Fürst spoke at the ceremony, urging the next generation to remember and protect human rights. Israeli officials objected to a planned speech by philosopher Omri Boehm, prompting organizers to withdraw the invitation.
