"I am a humanist and a patriot. I had serious problems because of my headscarf while I was a student and then as an academic at the university hospital. I had friends wearing headscarves who left school and had mental problems. I am grateful to President Recep Tayyip Erdogan because under his rule I was aware again that I was human. I had the right to work with clothes that expressed my way of being. Erdogan is in love with his nation. If 'Yes' wins, we will become a more respectful and powerful country. But some countries are not comfortable with Turkey becoming more powerful." REUTERS/Umit Bektas SEARCH "VOXPOPS UMIT" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.?

A forensic technician makes notes while performing an autopsy on a crime victim at the morgue of the Forensic Institute in San Salvador, July 7, 2015. In El Salvador the number of homicides surged 70 percent last year, making the central American nation among the most violent countries in the world. Violence and murders have risen steadily since a 2012 truce between the two main street gangs began to fall apart. Months of reporting show killings in the suburbs of the capital, San Salvador, where powerful gangs known as maras control entire neighbourhoods.

Forensic physicians carry out an autopsy on a unknown person at the morgue of Rosario, north of Buenos Aires, Argentina September 10, 2015. International drug-enforcement officials have taken to calling Rosario "The Tijuana of Argentina" for what it has in common with the Mexican border city used to move cocaine into the United States. Experts say the drug enters Argentina by truck or plane from Andean cocaine-producing countries to the north. The smuggling routes narrow the closer shipments get to Rosario, increasing violent competition among gangs to control the final steps toward the Parana River, which leads south to Buenos Aires and the shipping lanes of the Atlantic. Drug-related killings spiked so high in Rosario last year that federal forces were called in to provide security. To match story ARGENTINA-DRUGS/ Picture taken September 10, 2015.
