A primary school fire in Adelaide's northern suburbs that caused about $1 million worth of damage is being treated as suspicious.
Police and fire crews were called to John Hartley School on Peachey Road at Smithfield Plains at about 9:40pm on Sunday.
They arrived to find a block of classrooms on fire.
It took 32 firefighters from eight trucks, plus another two Country Fire Service crews 15 minutes to get the blaze under control, and another half an hour to extinguish it.
SA Police said there had been no reports of injuries and fire cause investigators would be at the school on Monday morning.
Principal Jo Everett said eight rooms had been gutted by the fire, affecting more than 180 students and 20 staff.
"All incidents of this nature are devastating to the school community and here at John Hartley will be no different," Ms Everett said.
"We'll be working with the education department and other support services to look after the wellbeing of staff and students … and we'll be planning next steps in the short term and the long term."
The school and children's centre will be completely closed on Tuesday and Wednesday.
"However, our staff will be on site and support will be available to any staff, students or families who require it," Ms Everett said.
At this stage, Ms Everett said she expects the school to be "partly open" on Thursday.
"Our school sports day – due to be held on Friday – will be postponed, but we expect the school to be open to all students that day. The students from the eight classrooms effected from the fire will be based in school gym," she said.
Emergency Services Minister Joe Szakacs described the incident as a tragedy.
"Places of safety, places of happiness, places of learning for our young children, it’s always a tragedy to see this," he said.
“It’s a selfish act, it’s a dumb act, it’s a criminal act, but lets wait to see what the investigation provides.”
Two of Sara Himsworth's children attend the school and their classes are in the building that has been burnt down.
"My son had woken me up and said 'the school's on fire' … so we came down and most of the fire had been put out by then," she said.
"It's disappointing, it's worrying for the little ones not knowing what they're going to have to go back to [or] when they will go back to school."
Seven-year-old Oliver Himsworth told ABC News the fire made him feel sad.
"Because all our class work is gone," he said.
In a separate incident, police are also investigating a drive-by shooting at a northern suburbs home in the early hours of this morning.
Senior Constable Jen Cullinan told ABC Radio Adelaide police were called to Bogart Drive at Paralowie after neighbours reported sounds of gunshots.
"When police arrived, they discovered six shots had been fired into the front of the premises, which had hit the guttering and the roller doors," she said.
"Thankfully nobody has been injured.
"It is quite early in the investigation, but we don't believe the incident was random."
Police are calling on anyone with information about either incident to contact Crime Stoppers.
