Greek Prime Minister Alexis Tsipras is meeting with European creditors today in Brussels in a bid to avoid default at the end of the month. In a Twitter post today, Tsipras said some creditors have not accepted Greece’s latest proposals for aid, which include restricting early retirement and increasing the sales tax and pension contributions. Protesters have continued to call for Tsipras’ Syriza party to comply with their election pledge to end austerity.
