MILAN, January 3 (Reuters): An agreement signed last year making the Vatican’s de facto recognition of Palestine in 2012 official has come into effect, the Holy See said on Saturday. The Vatican signed its first treaty with the “State of Palestine” last June when it called for moves to end the Israeli-Palestinian conflict and backed a two-state solution. “... the Holy See and the State of Palestine have notified each other that the procedural requirements for (the accord’s) entry into force have been fulfilled, the Vatican said in a statement on Saturday. The U.N. General Assembly adopted a resolution in 2012 recognising Palestine as an observer non-member state. This was welcomed at the time by the Vatican, which has the same observer non-member status at the United Nations. In October 2014, Sweden acknowledged Palestine, a decision that drew condemnation from Israel and led to tense relations between the two.
