Turkish authorities detained several journalists from their homes, a media workers' union reported on Monday, in what it said was a crackdown amid escalating protests triggered by the imprisonment of the mayor of Istanbul and top rival to President Recep Tayyip Erdogan.

On Sunday, a court formally arrested Mayor Ekrem Imamoglu and ordered him jailed pending a trial on corruption charges. His detention on Wednesday sparked the largest wave of street demonstrations in Turkiye in more than a decade, deepening concerns over democracy and the rule of law.

In an apparent escalation of the government's response to the growing protests, the Disk-Basin-Is union said at least eight reporters and photojournalists were detained in what it said was an "attack on press freedoms and the people's right to learn the truth". "You cannot hide the truth by silencing journalists!" the union wrote on the social media platform X, calling for their immediate release.

A total of 1,133 people have been detained since March 19, when the mayor was arrested at his home, Interior Minister Ali Yerlikaya said. As many as 123 police officers were injured in the protests, he said adding that dangerous materials such as acid, firebombs and knives were seized.

"Some circles have been exploiting the right to assemble and demonstrate, attempting to disrupt public order, incite street unrest, and attack our police," Yerlikaya said on his social media account. The minister said some of the detained were identified as having ties to groups listed as terrorist organisations.
