President Recep Tayyip Erdogan has addressed thousands of flag-waving supporters outside Istanbul's Ataturk Airport and tells them he is charge and coup won't succeed.

Prime Minister Binali Yildirim, speaking to state-run Anadolu Agency, says more than 120 people have been arrested in a coup plot.
He says: "Things are getting better every minute."
Yildirim called on people to remain in the streets to support the government against coup plotters and appealed for patience.
He says a few air force planes flown by coup plotters still remain in the air. He has earlier ordered those aircraft shot down.
President Recep Tayyip Erdogan says his general secretary was abducted by coup makers and there is no information on the chief of the military staff.
Prime Minister Binali Yildirim, speaking on NTV, says he has ordered the "annihilitation" of military planes used by coup plotters. He says military jets have taken off from an air base in Eskisehir, east of Ankara.
According to transcripts of the president's remarks provided by his office, Erdogan said that he arrived in Istanbul from the holiday resort of Marmaris, which was also been bombed after he left there.

The movement of the U.S.-based Islamic cleric Fethullah Gulen has denied any involvement in the Turkish military coup attempt.
The Alliance for Shared Values says "we condemn any military intervention in (the) domestic politics of Turkey."
Turkish President Recep Tayyip Erdogan has launched a broad campaign against Gulen's movement in Turkey and abroad. The Erdogan regime has carried out a purge of civil servants suspected of ties to the movement, seized businesses and closed some media organizations. Gulen has been charged criminally with plotting to overthrow the government, and was placed on trial in absentia in Turkey earlier this year.
As the crisis unfolded in Turkey, there were reports that access to popular social media sites like Twitter and Facebook had been blocked within the country. Facebook declined comment, but Twitter said it suspected "intentional" interference with its service.
The company said in a statement that "we have no reason to think we've been fully blocked in (hash)Turkey, but we suspect there is an intentional slowing of our traffic in country."
A spokesperson would not elaborate.
Separately, YouTube said in a statement: "We are aware of reports that YouTube is down in Turkey, however, our systems seem to be functioning normally."
Access to social media has been obstructed during previous periods of political upheaval in the country, according to some Internet watchdog groups, although Turkish authorities have denied involvement and suggested that technical problems were to blame.

They also collaborate in implementing an agreement with the European Union - monitored by NATO - to limit the number of refugees and migrants traveling to Europe.
State-run ERT television reported that Greek Prime Minister Alexis Tsipras had been briefed by intelligence and military leaders on the coup attempt in Turkey, including unusual movements by Turkish armed forces before the attempt became apparent.

Turkey's state-run Anadolu Agency says that 17 police officers have been killed in a helicopter attack on police special forces headquarters on the outskirts of Ankara.

Turkish Interior Minister Efkan Ala says very effective units from the chief of general staff's office, the Turkish armed forces and the police are responding to the attempted coup in the country.
Ala says they are responding to "gangs who have taken cover in certain locations."
He spoke by telephone to NTV television and also encouraged Turkish citizens to "fearlessly go out and support our security forces."
He says: "We think it would be right for them to go out to the airports, to the streets, especially to the main arteries. As long as they do that this gang's attempts... they will be defeated no matter what."
He added "this is a gang that considers nothing sacred, not the people or the nation. They're taking certain actions."
NATO hasn't responded immediately to a request for comment on how alliance operations or Turkey's status might be affected after the military said it seized control of the country.
Independent observers noted that the 1949 treaty that created the U.S. alliance has no mechanism for suspending members, unlike the United Nations, the European Union or the Organization of American States.
Nothing in NATO's founding 1949 Washington Treaty says anything about intervening in the internal or political affairs of an alliance member, and Turkey kept its NATO membership following past military coups.
The treaty's key clause, Article 5, stipulates that NATO member states agree that "an armed attack against one or more of them in Europe or North America shall be considered an attack against them all," but that language has taken to apply to an external enemy.
Loud explosions have been heard in Turkey's capital Ankara and CNN-Turk reports an explosion occurred at the state-run television building.
Turkey's state-run news agency report military helicopters have also attacked the headquarters of TURKSAT satellite station on the outskirts of Ankara and the Ankara Police headquarters.

Turkey's president has urged citizens to take to the streets in a show of support for the government after the military said it seized full control of the country.
Recep Tayyip Erdogan, speaking to CNN-Turk through FaceTime, called the actions by the military "an attempt at an uprising by a minority within our armed forces."
The president's office refused to disclose Erdogan's whereabouts, saying he was at a secure location. Erdogan said "I don't believe this coup attempt will be successful."
Erdogan added: "There is absolutely no chain of command here. Right now the chain of command has been put on hold."
The White House says President Barack Obama has been briefed on developments in key NATO ally Turkey where the military claims to have seized power in a coup.
The National Security Council said Obama had been apprised of Friday "unfolding situation" in Turkey and would continue to get regular updates.
U.S. Secretary of State John Kerry says he hopes for stability and continuity in Turkey following the reports.
Kerry, in Moscow for talks with Russian officials on Syria on Friday, told reporters he didn't have details of the situation rapidly unfolding on the ground in Turkey and said it would be "inappropriate" to comment on developments.

Turkey had long been a popular vacation destination for Russians, but the numbers dropped sharply last year when Russia banned package tours to Turkey amid tensions over Turkey shooting down a Russian warplane and it was unclear how many Russians currently are in the country.
