The expected announcement Tuesday of Turkish Prime Minister Recep Tayyip Erdogan's candidacy for the upcoming presidential in elections on August 10 is the main story in most of the Turkish press.

"Twelfth president becoming clear," is the headline in YENI SAFAK. The paper says that Erdogan will announce his candidacy during a ceremony attended by 4,000 guests including 270 foreign and local journalists in Ankara. The next Turkish president will be the country's 12th president.

The ruling party's candidate will be "someone the world knows," the daily cites Turkish Deputy PM Bulent Arinc as saying.

"A three-candidate race" is the headline in the daily CUMHURIYET, referring to the main opposition Republican People's Party's candidate Ekmeleddin Ihsanoglu, co-chairperson Selahattin Demirtas of the pro-Kurdish Peoples' Democracy Party and Erdogan as the likely nominee from AK Party, according to the newspaper.

"Historical day" says daily TURKIYE, adding that Erdogan's candidacy will be announced with a "show of strength."

The hoisting of the black flag of the Sunni militant group Islamic State of Iraq and the Levant, or ISIL, across from the southern Turkish town of Akcakale along the Syrian border and reaction to the announcement of militant group's founding of an Islamic state is covered by Turkish dailies as well.

"Black flag again at border" is the headline in the daily VATAN. ISIL have hoisted their flag in the Syrian town of Tal Abyad, says the paper.

The daily added that ISIL has also renamed itself "Islamic State."

"Caliphate announcement from ISIL," daily SABAH headlined, stressing ISIL has changed its name and announced their leader Abu Bakr al-Baghdadi as the "caliph." The militants have also called the world to "obey" to the authority of the Islamic caliphate, according to the daily.

Some dailies also covered the announcement of pro-Kurdish opposition People's Democratic Party's co-leader Demirtas to run as the party's candidate in the presidential elections.

Daily VATAN reported that Demirtas was the youngest nominee for the elections amongst other candidates with the headline "Race starts." Comparing Erdogan, Ihsanoglu and Demirtas, the daily quotes Demirtas as saying "We will show that the state can smile," and he lamented the absence of any female candidates for president.
