A man shoots and kills his uncle at a school in southern Turkey

ISTANBUL — A man shot and killed his uncle at a school in southern Turkey on Monday, officials said, the latest shooting to hit the country and one that has raised concerns about safety at educational facilities and the proliferation of guns.

The 41-year-old gunman shot his uncle, Mehmet Bilgili, a Turkish language and literature teacher, in the yard of Farabi Anatolian High School in Cardak, on the outskirts of the city of Osmaniye, Provincial Gov. Mehmet Fatih Serdengecti said.

The suspect shot Bilgili with an unlicensed handgun following an argument before he was detained, Cumhuriyet newspaper and other outlets reported.

Bilgili was taken to a hospital but died shortly afterward.

In a statement, the Education Ministry said the gunman was tackled by two security guards, one of whom was armed, and handed over to police.

Serdengecti said the man had been undergoing psychiatric treatment “for many years” and had fallen out with his uncle.

Adem Yucel, who heads the Osmaniye branch of teachers’ union Egitim-Is, questioned how an armed man was able to enter the school grounds.

“We want schools where our children go to school without fear, our teachers perform their duties safely and parents send their children to school with peace of mind,” he said.

The shooting came after a 15-year-old student wounded 11 of his classmates when he opened fire with a shotgun last week at a school in Turgutlu, western Manisa province.

Turkey was shocked by two school shootings in as many days in April, leading to increased security at educational facilities at the start of the academic year this month.

The first incident saw 16 people, mostly students, wounded when a former student opened fire at a high school in the southeastern province of Sanliurfa. The assailant later killed himself.

The following day, a 14-year-old student attacked two classrooms at his school in nearby Kahramanmaras province, killing eight students and a teacher and wounding 13 others. The attacker was killed by police.

In the wake of the April shootings, President Recep Tayyip Erdogan pledged to make school safety a top priority and to tighten gun ownership regulations.

According to the Hope Foundation, which lobbies for greater gun control, more than 26,000 people have been killed in armed incidents, including by weapons other than guns, since 2014. Last year, there were 2,784 violent crimes involving firearms.
