WikiLeaks said on Monday it was planning to release documents on Turkey's political power structure after a failed coup attempt over the weekend.
WikiLeaks tweeted:
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.
President Tayyip Erdogan and the government accused the US-based Muslim cleric Fethullah Gulen, a former ally whom Erdogan accuses of trying to create a "parallel structure" within the courts, police, armed forces and media, of orchestrating the coup.
Erdogan's supporters of 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 (EU).
"We cannot ignore this demand," Erdogan told the chanting crowd. "In democracies, whatever the people say has to happen."
He said a "terror group" led by Gulen had "ruined" the armed forces, that its members were being arrested in all military ranks, and that a purge of this "virus" would continue. Gulen denied any connection with the coup.
