By Karolina Tagaris ATHENS (Reuters) - Employees at Greece's state television ERT hugged each other and cried on Thursday as the channel aired its first broadcast in two years, after it was shut down under one of the previous government's most drastic austerity measures. Leftist Prime Minister Alexis Tsipras, who is racing to reach a cash-for-reforms deal with the European Union and IMF, had called ERT's closure "a great wound" of his country's bailout.
