Riot police stand guard near Taksim Square to prevent protesters from defing a ban to celebrate May Day in Istanbul.
Members of the Greek communist labour union (PAME) gesture as they demonstrate in central Athens during the May Day celebrations on May 1, 2017. Greek trade unions marked May Day on Monday with a 24-hour nationwide strike and protests against looming new cuts demanded by the country's creditors in return for bailout cash. Under pressure from its creditors -- the European Union, European Central Bank and the International Monetary Fund -- the government agreed to adopt another 3.6 billion euros ($3.8 billion) in cuts in 2019 and 2020.
