Turkish President Recep Tayyip Erdogan told the nation Saturday that his government was working to crush a coup attempt after a night of explosions, air battles and gunfire across the capital.
"The coup attempt has been foiled", General Umit Dundar said in televised appearance, adding that 90 people - 41 of them police and 47 are civilians - "fell martrys".
He successfully mustered large crowds of supporters who took to the streets in cities across the country and in some cases confronted soldiers carrying out the coup. The senior official told The Associated Press that all government officials were in charge of their offices.
The Anadolu Agency says Saturday the helicopter was brought down in the Golbasi district, in the outskirts of Ankara. However, gunfire is still underway between the rebels and pro-Erdogan forces.
Order was restored early Saturday, Prime Minister Binali Yildirim said. The state-run news agency said more than 750 soldiers have been detained across the country.
Radio and TV channels went off air, but members of the government made it through to those still broadcasting - most memorably, President Recep Tayyip Erdogan, appearing on CNN Turk via mobile-phone video link - to encourage the population not to give in.
"Some flights to airports in Turkey are being diverted or cancelled, and the bridges across the Bosphorus in Istanbul have been closed".
He said the act was encourage by the "parallel structure" - his shorthand for followers of Fethullah Gulen, a U.S.-based Muslim cleric who he has repeatedly accused of attempting to foment an uprising among his followers in the judiciary and the military. I call for calm and restraint, and full respect for Turkey's democratic institutions and its constitution.
1,154 people were wounded, he said before warning that anyone who betrays the country will not go unpunished. "Let us gather in our squares, at our airports as the people, and let that minority group come upon as with their tanks and artillery and do whatever they wish to do", Erdogan said.
"Those who are attempting a coup will not succeed".
The president of a group that promotes Gulen's ideas, the New York-based Alliance for Shared Values, denied the charges.
Turkey is also one of the main backers of opponents of Syrian President Bashar al-Assad in that country's civil war, host to 2.7 million Syrian refugees and launchpad previous year for the biggest influx of migrants to Europe since World War Two.
NTV television is quoting the prosecutor's office in Ankara saying at least 42 people have been killed in "attacks" in the capital. There have been no reports so far of Indian casualties and the foreign ministry has opened helplines in Istanbul and Ankara. "We strongly hope that the situation will return to normal, and that order and peace will be restored as soon as possible", Abe said in a statement. The military has a history of mounting coups to defend secularism, but has not seized power directly since 1980.
The government calls Gulen's supporters a "terrorist group" that has long plotted to overthrow the country's elected government.
