"The Turks were on notice that.it was time for Pastor Brunson to be returned", Pompeo told reporters in Singapore.
The standoff appears to be one of the most serious crises between Turkey and the United States in modern history, along with the rows over the 1974 Turkish invasion of Cyprus and the 2003 US-led invasion of Iraq.
Also Turkish Foreign Minister said he told US Secretary of State Mike Pompeo that threats and sanctions will not work, after Washington targeted Turkish ministers over the detention of an American pastor.
Mr. Brunson had denied all charges and his case has become a cause celebre for USA evangelicals and the Trump administration. Turkey has said the sanctions are unacceptable.

The meeting was the first between the countries' officials after Ankara vowed it would respond to sanctions with retaliatory measures. "We repeated this today", he said after a meeting with the US Secretary of State Mike Pompeo in Singapore.
The Turkish foreign ministry called the sanctions a "disrespectful intervention in our legal system" that would harm "the constructive efforts toward resolving problems between the two countries".
Pompeo said the administration's actions on Wednesday - imposing sanctions on Turkey's justice and interior ministers - were a sign of how seriously the U.S.is treating Brunson's case.
Pastor Andrew Brunson was held in prison for almost two years before he was moved to house arrest last week, disappointing American officials who expected his release.
The sanctions freeze any property or assets on U.S. soil held by the two ministers, and bar U.S. citizens from doing business with them. Americans would generally be prohibited from doing business with them.
He was recently released from prison and put under house arrest but still faces a sentence of up to 35 years if he is convicted at his ongoing trial. Ankara blames Gulen for the coup attempt, while the cleric denies involvement.
