Turkey widened a crackdown on suspected supporters of a failed military coup on Sunday, taking the number of people rounded up in the armed forces and judiciary to 6,000, and the government said it was in control of the country and economy.
Supporters of President Tayyip Erdogan gathered in front of his Istanbul home to call for the plotters to face the death penalty, which Turkey outlawed in 2004 as part of its efforts to join the European Union.
"We cannot ignore this demand," Erdogan told the chanting crowd. "In democracies, whatever the people say has to happen."
Pictures on social media showed detained soldiers stripped from the waist up, some wearing only their underpants, handcuffed and lying packed together on the floor of a sports hall where they were being held in Ankara.
One video on Twitter showed detained generals with bruises and bandages. Akin Ozturk, head of the air force until 2015 and identified by three senior officials as one of the suspected masterminds of the coup plot, was among those held.
The Foreign Ministry raised the death toll to more than 290, including over 100 rebels, and said 1,400 people were hurt.
The violence shocked the nation of almost 80 million, once seen as a model Muslim democracy, where living standards have risen steadily for more than a decade and where the army last used force to stage a successful coup more than 30 years ago.
It also shattered fragile confidence among Turkey's allies about security in the NATO country, which is a leading member of the U.S.-led coalition against Islamic State. Turkey had already been hit by repeated suicide bombings over the past year and is struggling to contain an insurgency by Kurdish separatists.
With expectations growing of heavy measures against dissent, European politicians warned Erdogan the coup attempt did not give him a blank cheque to disregard the rule of law, and that he risked isolating himself internationally as he strengthens his position at home.
Broadcaster NTV cited Justice Minister Bekir Bozdag as saying more arrests were expected.
Authorities have rounded up nearly 3,000 suspected military plotters, ranging from top commanders to foot soldiers, and the same number of judges and prosecutors after forces loyal to Erdogan crushed the attempted coup on Saturday.
Among those arrested was General Bekir Ercan Van, commander of the Incirlik air base from which U.S. aircraft launch air strikes on Islamic State militants in Syria and Iraq, an official said. Erdogan's chief military assistant was also detained, broadcaster CNN Turk said.
'NATIONAL WILL'
On Sunday, security forces clashed with remnants of the coup plotters at Istanbul's second airport and at an air base in central Turkey, an official said, adding that arrests were made and the situation was under control.
Erdogan said the coup had been put down by the "national will", blaming "those who cannot bear the unity of our country and are under the orders of masterminds to take over the state".
He frequently refers to "masterminds" who he says are bent on breaking up Turkey, in what appears to be a veiled reference to the West in general, and more specifically, the United States.
On Saturday, Labour Minister Suleyman Soylu told broadcaster Haberturk he believed Washington was behind the coup attempt. U.S. Secretary of State John Kerry described public suggestions of a U.S. role as "utterly false", and said on Sunday that Washington had had no advance intelligence of the coup.
The Pentagon also announced on Sunday that operations from Turkey by the U.S.-led coalition against Islamic State had resumed after Ankara reopened its air space, which had been closed during the coup attempt.
However, U.S. facilities at the Incirlik base were still operating on internal power sources after Turkey cut the mains power supply. Kerry said the difficulty for U.S. planes using the base may have been a result of Turkish aircraft flown in support of the coup using it to refuel.
'PARALLEL STRUCTURE'
The crackdown intensifies a long-standing push by Erdogan to root out the influence of followers of U.S.-based cleric Fethullah Gulen.
Erdogan accuses followers of Gulen, who was once an ally but is now his arch-enemy, of trying to create a "parallel structure" within the courts, police, armed forces and media, with an aim to topple the state.
The cleric has denied this and said he played no role in the attempted coup, denouncing it as an affront to democracy. On Sunday, he told reporters he believed Erdogan had staged the coup, and that he would obey any extradition order.
Erdogan said Turkey's justice and foreign ministries would write to Western governments to demand the return of Gulen's supporters from those countries.
Kerry said he had no evidence Gulen was behind the plot to seize power, and he urged Turkish authorities to compile evidence as rapidly as possible so the United States could evaluate whether he should be extradited.
Even before the coup attempt was over, Erdogan promised a purge of the armed forces. "They will pay a heavy price for this," he said. "This uprising is a gift from God to us because this will be a reason to cleanse our army."
At a rally late on Saturday, his supporters also demanded the coup leaders be executed. "Let's hang them!" chanted the crowd in Ankara's central Kizilay square.
Erdogan's critics say he will use the purge to create a pliant judiciary, eliminating dissenting voices in the courts.
Some European politicians have expressed unease about developments since the coup attempt.
"(The coup attempt) is not a blank cheque for Mr Erdogan. There cannot be purges, the rule of law must work," French Foreign Minister Jean-Marc Ayrault said.
Ayrault told France 3 television that European Union ministers would reiterate on Monday when they meet in Brussels that Turkey, which has applied to join the bloc, must conform to Europe's democratic principles.
European Commissioner Guenther Oettinger said Erdogan would move Turkey away from the core values represented by the EU and the NATO defence alliance if he decided to use the attempted coup to restrict basic democratic rights further.
"He would strengthen his position domestically, but he would isolate himself internationally," Oettinger, an ally of German Chancellor Angela Merkel, told Welt am Sonntag newspaper.
Some European politicians are also expressing concern about the future of a deal between the EU and Turkey that has helped to slow the numbers of migrants crossing from the country to neighbouring Greece.
STRAINED RELATIONS
A successful overthrow of Erdogan, who has ruled the country since 2003, would have marked another seismic shift in the Middle East, five years after the Arab uprisings erupted and plunged Turkey's southern neighbour Syria into civil war.
But the failed attempt could still destabilise the U.S. ally, which lies between Europe and the chaos of Syria.
Erdogan's Islamist-rooted AK Party has long had strained relations with the military, which has a history of mounting coups to defend secularism although it has not seized power directly since 1980.
His conservative religious vision for Turkey's future has also alienated many ordinary citizens who accuse him of authoritarianism. Police used heavy force in 2013 to suppress mass protests demanding more freedom.
However, Erdogan commands the admiration and loyalty of millions of Turks particularly for raising living standards and restoring order to an economy once beset by regular crises.
'NECESSARY MEASURES'
Deputy Prime Minister Mehmet Simsek took to Twitter to try to reassure investors the government was in full control of the economy before financial markets opened on Monday.
"The macro fundamentals of our country are solid. We are taking all necessary precautions. We are strong with the support of our people and strengthened political stability," he said on Twitter, adding that he planned to hold a conference call with global investors on Sunday.
The central bank said it would provide unlimited liquidity to banks.
For at least eight hours overnight on Friday violence shook Turkey's two main cities. But the coup attempt crumbled as Erdogan rushed back to Istanbul from a Mediterranean holiday and urged people to take to the streets in support of his government against plotters he accused of trying to kill him.
U.S. President Barack Obama has also urged parties on all sides of the crisis to avoid destabilising Turkey and follow the rule of law.
