The United States has announced this Thursday that it will withdraw from UNESCO, the United Nations Educational, Scientific and Cultural Organization, to consider it an organism "with a bias contrary to Israel". The decision will be effective on December 31, 2018, according to the U.S. government communiqué. The Director-General of Unesco, Irina Bokova, announced the decision of Washington, after having already suspended in 2011 the payment of their contributions. The head of the UN's Organization for Education, Culture and Science said in a statement that U.S. Secretary of State Rex Tillerson has officially notified that decision, that she "deeply regrets" and considers "a loss to the Multilateralism, "reports Efe. Washington will establish an "observation mission" in this UN body, replacing its representation as a member, said State Department spokeswoman Heather Nauert.
