A protester looks at policemen standing behind teargas during riots at central Syntagma square in Athens April 4, 2012. Greek police fired teargas to disperse hundreds of protesters taking part in a rally commemorating the death of a Greek pensioner who shot and killed himself in Athens’ parliament square on Wednesday after crying out to bystanders that crippling debts had pushed him to take his life. Suicides have risen in Greece as a deepening economic crisis leaves one in five jobless and countless more struggling to survive on sharply reduced salaries and pensions.
