Istanbul is the most populous city in Turkey and the country's economic, cultural and historic center. It is located in north-western Turkey within the Marmara Region.
The Bosphorus, which connects the Sea of Marmara to the Black Sea, divides the city into a European (Thracian side), and an Asian (Anatolian side). The city is also divided by the Golden Horn, a natural harbor bounding the peninsula where the former Byzantium and Constantinople were founded.
Turkey has celebrated its annual press freedom day by putting 17 opposition newspaper staff on trial for terrorism. They stand accused of collaborating with the very organizations they had criticized.
Turkey remains in the grip of emergency rule. Since last July's failed coup, over 60,000 have been detained and more than a 140,000 purged from their jobs. But that crackdown is facing what could be its greatest challenge yet: because one man decided to walk from the capital Ankara to Istanbul, holding a simple placard with the word justice. He's since been joined by thousands.
Organizers of a gay pride parade in Istanbul had said they would go ahead with a march despite a ban. But using tear gas and rubber bullets, police prevented large numbers of people from gathering together.
It was the UN World Refugee Day on Tuesday and for the third successive year, Turkey was designated the country hosting the most refugees. There are currently over 3 million Syrians and Iraqis who have sought sanctuary in Turkey. But as Dorian Jones reports from Istanbul, while the government continues to welcome the refugees, there are growing tensions about their presence in the country.
