ATHENS/BRUSSELS (Reuters) – Greece sent its euro zone partners an augmented list of proposed reforms on Friday but EU officials said several more steps were required before any release of aid funds to a country that Prime Minister Alexis Tsipras says has a noose around its neck. Struggling to scrape together cash and avoid possible default, Athens made a 310 million euro partial loan repayment to the International Monetary Fund, while Tsipras pleaded to be allowed to issue more short-term debt to plug a funding gap.
