Turkey's state broadcaster TRT will screen Sunday's major 'Democracy and Martyrs' Rally' in seven languages live on social media.

In addition to the live broadcast, the event in the Yenikapı district in Istanbul will also be streamed on YouTube in Turkish, English, French, Spanish, German, Russian and Arabic.

Millions of people are gathering in Istanbul ahead of the cross-party 'Democracy and Martyrs' Rally' called to protest the defeated July 15 coup launched by the Gülenist TerrorOrganization (FETÖ).

People started to gather hours before the mass rally in the city's Yenikapi district, many carrying national flags.

The Yenikapı rally is to be addressed by President Recep Tayyip Erdoğan and Prime Minister Binali Yıldırım, who is also the leader of the ruling Justice and Development (AK) Party.

Leader of the main opposition Republican People's Party (CHP) Kemal Kılıçdaroğlu and Nationalist Movement Party (MHP) leader Devlet Bahceli have confirmed they will attend the rally which will start at 5 p.m. local time (1400GMT). A collection of Turkish celebrities will also be at the event.

Turkey's government has repeatedly said the defeated attempt was organized by followers of Fetullah Gülen, who has lived in self-imposed exile in the U.S. state of Pennsylvania since 1997.

Gülen is also accused of leading a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary, forming what is commonly known as the parallel state.
