President Recep Tayyip Erdogan of Turkey has announced a three-month extension of the state of emergency imposed after a failed July 15 coup attempt, giving him broad powers to rule by decree.

He has launched a massive crackdown against followers of the self-exiled cleric Fethullah Gulen, whom Erdogan accuses of instigating the attempted overthrow. Gulen denies it.

More than 30,000 Turkish citizens have been arrested and upward of 100,000 people accused, many without due process. Last week, authorities announced that 12,800 police officers had been suspended on suspicion of being part of Gulen’s network.

Journalists have been in Erdogan’s crosshairs, and his campaign is pushing into the digital universe, too. Turkey is pressing Twitter to silence journalists, and Twitter must resist more vigorously.

Erdogan briefly banned Twitter in 2014 to block messages about a corruption scandal. After Twitter returned, Turkish authorities submitted long lists of accounts they wanted banned, but Twitter, for the most part, protected journalists and did not switch them off. After the coup attempt, however, new court orders were issued and Twitter was asked to hush accounts, some belonging to journalists from the newspaper Zaman, close to the Gulen movement, that was seized in March and then shuttered. Twitter has switched off a number of the accounts.

Turkey has asked Twitter to restrict accounts more often this year than any other country in the world, according to Twitter’s transparency reports; Turkey made 2,493 requests covering 14,953 accounts, and Twitter complied 23 percent of the time.

Twitter should keep journalists’ accounts open and not become a tool of repression for Erdogan.
