Schools should not be turned into a "battleground" around potential safety measures, the key figure overseeing child rights in Wales has said.
Roccio Cifuentes, Children's Commissioner for Wales, was speaking after a 14-year-old girl was convicted of the attempted murder of three people during a school stabbing in Ammanford, Carmarthenshire, last April.
Ms Cifuentes said she agreed with the chief inspector of the Welsh education watchdog, Estyn, about not having a blanket exclusion policy.
"Schools have to be a safe space for everyone, pupils and teachers alike," Ms Cifuentes said.
