Ružić says it is "unthinkable, how, when you see the scene of the incident, what the children have been through".
He says the government is proclaiming a three-day mourning period across Serbia starting from Friday 5 May until 7 May.
School will be suspended and there will be no classes today, and tomorrow they will start with a minute of silence, he says.
Serbia's education minister is still speaking: "We pray to God to help all those hospitalised and injured", referencing the six children and a teacher who have been hospitalised."
He says Serbians are "grateful to the bravery of the teachers and all those in the school who tried to stop this tragedy".
He also says psychologists are here to support everyone affected.
Education Minister Branko Ružić is speaking first. He says eight children and a security guard sadly lost their lives.
No one can give those children back to their parents, he tells reporters.
He confirms the incident happened this morning around 08:40 local time (07:40 BST) when a student from the "seventh grade committed this bestial act.. the first in Serbia".
Serbian officials have begun a press conference following this morning's school shooting with a moment's silence.
We're now expecting to hear from the country's Education Minister Branko Ružić, Health Minister Danica Grujičić and a police spokesman.

People comfort each other at scene of Belgrade shooting

BBC News, Serbia
“She has long hair and black jeans”, crying and shaking, a mother of one of the children from Vladislav Ribnikar elementary school in Belgrade is repeating again and again over the phone.
She and other parents are calling every doctor and hospital in Belgrade they know.
It’s been a couple of hours since the shooting and they still don’t know if their children are alive and well.
"My daughter is not answering her phone, her teacher as well, and the shooting happened in her class”, one of the fathers tells us.
The streets around the school are in complete silence and anticipation - broken only, from time to time, by crying parents.
“Please tell us anything”, they are shouting at police officers.
A couple of hours ago, officers released a number of younger students from the school, one class at a time. Parents rushed to meet and hug them, with eyes full of tears of joy.
Teachers, students and parents have been comforting each other outside the elementary school in central Belgrade where the shooting took place.
Here are some of the latest pictures from the scene:

He says the shooting happened at one of the most prestigious primary schools in the capital, during a history class.
Six very young pupils from the same class and their history teacher are in different hospitals in Belgrade being treated for their wounds, he says.

He says there's been a lot of debate about whether the weapons and arms belonging to people in the Balkans, after the wars in the 1990s, are listed and registered, and how that information is kept and stored.
"This event will certainly open a big discussion on what has been done in the past," he says, adding there's been a lot of shock and a lot of silence since the incident.
Police officers and emergency services have cordoned off the area around the school where the shooting happened.

Milan Milosevic, the father of one of the pupils at the school, said his daughter was in the class where the gun was fired and managed to escape.
"[The boy] first shot the teacher and then he started shooting randomly," Milosevic told broadcaster N1.
"I saw the security guard lying under the table. I saw two girls with blood on their shirts. They say he [the shooter] was quiet and a good pupil. He recently joined their class."

The shooting started at around 08:00 local time at the Vladislav Ribnikar school, in Belgrade's central Vracar district.
Officers arrested a 14-year-old boy and took him away from the scene, with his hands cuffed and his head covered with a jacket.
The suspect's classmates say he walked into a History class, first shot the teacher and then turned his weapon on his fellow students.
He also allegedly shot at least one security guard who tried to prevent him entering the school.
The incident is causing enormous shock in Serbia.
Despite widespread weapon ownership, gun crime is rare - and school shootings unheard of.
