during which Cyprus was forced to manage a heavy flow of refugees and aid out of and into Lebanon. However, the discovery of natural gas in the Leviathan gas field led to a thawing of relations between the two governments. The two countries demarcated their Exclusive Economic Zones in 2010. Israel's rising antagonism with Turkey further increased the level of cooperation between the two countries, as Israel compensated by improving its relations elsewhere. In February 2012, Netanyahu visited Cyprus, the first visit of an Israeli Prime Minister in history. The collaboration between Cyprus, Israel and Greece on natural gas extraction has been characterised by the media as the Energy Triangle. Cyprus serves an important role as the place where most Israeli couples obtain civil marriages, because Cyprus is the closest country on good diplomatic terms with Israel that issues civil marriages. Israel does not issue civil marriages, only religious ones, with religious restrictions on the eligibility of marriage, and a recent law allows civil marriages in Israel under one condition: both individuals are non-Jewish residents of the state. Israel does however recognize civil marriages issued abroad, with Cyprus being the largest source of easy civil marriage licenses. Relations between Israel and Cyprus are based on mutual respect for Western values, the support for free-market economy and the establishment of democracies in the Middle East that would co-exist peacefully. Czech Republic Israel and the Czech Republic share a special relationship. Czechoslovakia was the only country to send aid to Israel in its early years e.g. arms shipments from Czechoslovakia to Israel 1947–1949. In December 2008, the Czech Air Force wanted to train in desert conditions for the upcoming mission in Afghanistan. No country agreed to help, except Israel. Israel saw it as an opportunity to thank the Czechs for training Israeli pilots when the country was first established. Denmark The relations between Denmark and Israel have been friendly and warm. Denmark voted for the partition of Palestine in 1947 and supports Israel in the United Nations. Denmark was one of few countries in Europe to save most of its Jewish population during the WWII. In Jerusalem, there is a monument to the rescue of Danish Jews, a school is named in Denmark's honor, and the King Christian X hospital in Eitanim is named after Denmark's king during World War II. Denmark has an embassy in Israel, and Israel has an embassy
