A shooter killed at least eight people and injured 13 in a drive-by attack near a town close to Belgrade on Thursday, as reported by the news agency AP. This is the second such incident in two days. The suspect randomly shot at people near the town Mladenovac, some 50 kilometers south of the capital, as reported by RTS Television on Friday. Serbian police said early Friday that they had arrested  the suspect, as reported by AP. The shooting incident came just a day after a 13 year old boy used his father’s gun in a rampage at school in Belgrade that led to the killing of eight students and a school security guard.


The father of the student at the school in central Belgrade said the shooter entered his daughter's classroom, firing at her teacher and then her classmates as they ducked under their desks.


Most students were able to flee through a back door, according to a local official. Senior police official Veselin Milic said the shooter drew sketches of classrooms and wrote a list of children he planned to “liquidate" in an attack he planned for a month. Milic said Kosta Kecmanovic called police himself when the attack was over.


Earlier, police said Kecmanovic was a student at the Vladislav Ribnikar school and was born in 2009. They said he used his father's gun. Six more children and a teacher were also hospitalised in the attack. Local media footage showed a commotion as police removed Kecmanovic, whose head was covered as officers led him to a car.


Police sealed off the blocks around Vladislav Ribnikar, which is what's known as a primary school, whose students would typically range in age from 6 to 15. Authorities later carried body bags to a waiting van. Mass shootings are extremely rare in Serbia and in the wider Balkan region; none were reported at schools in recent years.


In the last mass shooting, a Balkan war veteran in 2013 killed 13 people in a central Serbian village. Experts, however, have repeatedly warned of the danger posed by the large number of weapons in the country after the wars of the 1990s. They also note that decades of instability stemming from the conflicts as well as the ongoing economic hardship could trigger such outbursts.


Police said they received a call about the shooting at around 8:40 a.m. on the first day that classes resumed after a long weekend for the May 1 holiday. “I was able to hear the shooting. It was nonstop,” said a student who was in a sports class when gunfire erupted elsewhere in the building. Her mother asked that her name be withheld because of her age.
