About 10 people were killed by the O’Bro School Campus attack.

The police say about 10 people were killed in a shooting case at a central Swedish training center, including suspected gunmen.

Prime Minister ULF Kristersson explained Tuesday attacks on Risbergska School in 200km (124 miles) Orebro from Stockholm on Tuesday.

The police believe that male offenders are dead and formerly unknown to them. They said they did not immediately identify, and he was considered to be acting alone.

Chrisson said at a press conference, “It’s hard to take the scale of what happened today.”

The police warned that the number of deaths could continue to increase when some people were injured.

Many injuries have been taken to the hospital and at least four people are undergoing surgery.

The police said five people were shot and that the case was investigated by murder, arson and weighted inorganic crimes.

Local media later said that the police began to say that some people died before saying that people were killed, but they were “not more specific.”

They also confirmed that they seemed to be “terror” motivated after the attack.

The police have heard that shootings occurred at 12:33 local time (11:44 GMT) at the Risbergska School. This facility is located on campus with other schools.

This center is mainly attended by people who have not completed elementary school or secondary school.

Previously, students from some of the nearby schools were maintained indoors for security purposes.

Roberto Eid Forest, the chief of the police, warned that “we do not want the public to go there.”

The Attorney General, who appeared with the prime minister on Tuesday evening, expressed mourning to those who were influenced by the “tragedy” and reassured the citizens that citizens were safe to return on Wednesday.

“(I have never seen this scale school shooting case,” Gunnar Strommer said.

Nearby hospitals have cleaned the emergency room and intensive care room so that they can secure space for patients, local media reported.

Orebro University Hospital said five people who were injured by gunshot were treated in the emergency room. The sixth person who was not injured by a gun said that “minor injuries” were treated.

Orebro County’s local government said that there were no children in the update.

Lena Warenmark Teacher spoke to SVT, a Swedish public radio.

At the beginning of that day, Prime Minister Crystuson mentioned the day that is very painful for everyone in Sweden today.

Kristerson said, “It is a nightmare that no one needs to be experienced to be trapped in a classroom with fear of life.”

He later emphasized that there was no risk of attending school the next day and asked the police to give the space necessary to do freedom and work.

Kristersson added that the police and the Swedish government will share more information.
