ISTANBUL (Reuters)—Turkey’s prime minister said he had no regard for Europe’s “red line” on press freedom on Tuesday and warned Ankara would not be brought to heel with threats, rejecting criticism of the detention of senior journalists at an opposition newspaper.

Police detained the editor and top staff of Cumhuriyet, a pillar of the country’s secularist establishment, on Monday, on accusations that the newspaper’s coverage had helped precipitate a failed military coup in July.

The United States and European Union both voiced concern about the move in Turkey, a NATO ally which aspires to EU membership. European Parliament President Martin Schulz wrote on Twitter that the detentions marked the crossing of ‘yet another red-line’ against freedom of expression in the country.

“Brother, we don’t care about your red line. It’s the people who draw the red line. What importance does your line have,” Prime Minister Binali Yildirim told members of his ruling AK Party in a speech in parliament.

“Turkey is not a country to be brought in line with salvoes and threats. Turkey gets its power from the people and would be held accountable by the people.”

Prosecutors accuse staff at Cumhuriyet, one of few media outlets still critical of President Tayyip Erdogan, of committing crimes on behalf of Kurdish militants and the network of Fethullah Gulen, a U.S.-based cleric blamed for orchestrating the July coup attempt.

Journalists at the paper were suspected of seeking to precipitate the coup through “subliminal messages” in their columns before it happened, the state-run Anadolu agency said.

Cumhuriyet vowed “we will not surrender” in a front-page headline. Dozens of people staged a vigil in front of its Istanbul offices overnight, some wrapped in blankets as they slept on benches while police guarded barriers outside.

“Even if Cumhuriyet’s executives and writers are detained, our newspaper will continue its fight for democracy and freedom to the end,” it said in a defiant editorial which described the arrests as the start of an attempt to close the paper.

It said its pages had repeatedly warned that Gulen’s movement represented a danger to the Republic and wanted to abolish secularism. The paper said it had in the past been targeted by prosecutors and judges aligned with Gulen.

Turkey’s authorities have bristled at the Western reaction to the abortive coup, in which rogue soldiers used fighter jets and tanks to attack parliament and other key buildings, killing more than 240 people, many of them civilians.

They see European leaders as quick to condemn widescale purges of suspected plotters, but reluctant to accept the gravity of the putsch and the threat to the state.

“We have no problem with press freedom. This is what we can’t agree with our European friends. They always bring up press freedom when we take steps in our fight against terrorism,” Yildirim said.

He said Turkey could draft a “limited measure” to bring back the death penalty if a political compromise could be reached on the issue, a move that could spell an end to its efforts to join the European Union.

Crowds have repeatedly called for the re-introduction of capital punishment, which Turkey abolished in 2002 as part of the EU accession process, and Erdogan has said he would approve it if parliament voted for it.
