By Renee Maltezou and Andreas Rinke BRUSSELS (Reuters) - Euro zone leaders told near-bankrupt Greece at an emergency summit on Sunday that it must restore trust by enacting key reforms before they will open talks on a new financial rescue to keep it in the European currency area. Leftist Prime Minister Alexis Tsipras will be required to push legislation through parliament from Monday to convince his 18 partners in the monetary union to release immediate funds to avert a Greek state bankruptcy and start negotiations on a third bailout programme. Tsipras said on arrival in Brussels he wanted "another honest compromise" to keep Europe united.
