Turkish police have ordered the arrests of 83 people accused of posting controversial content online about two deadly school shootings which took place this week.
They were found to have engaged in posts and activities praising crime and criminals and negatively affecting public order, police said.
It added that access to 940 social media accounts have been blocked and 93 Telegram groups have been shut down.
At least nine people were killed in a shooting at a school in southern Turkey on Wednesday, a day after another attack injured 16 people at a high school in the country's southeast.
At least eight students and one teacher were killed in the school shooting in the Kahramanmaras area of southern Turkey. Turkish officials said 13 others were wounded, with six in critical condition.
A 14-year-old attacker was also killed during the incident at Ayser Calik Secondary School.
The local prosecutor's office in the Kahramanmaras province stated that the suspect had planned the attack in advance, with materials found that indicated intent for a major operation.
The suspect had referenced US mass killer Elliot Rodger in a photo on his WhatsApp profile, according to police. Rodger, a 22-year-old American, murdered six people before taking his own life in California in 2014.
Turkish media reported that the attacker, believed to be a student, entered two classrooms and had five guns and seven magazines with him.
The aunt of a victim mentioned she learned her 10-year-old niece had been killed when her name was read out on the news.
Funeral prayers for four of the victims were held in the city's main mosque with several government ministers in attendance.
This shooting was the second in the country within the week, following another incident where an ex-student opened fire at Ahmet Koyuncu Vocational and Technical Anatolian High School, injuring 16 individuals.
Both incidents have sparked public outrage and calls for more stringent measures against online discourse that glorifies violence.
