A pipe bomb has been made safe after it was discovered on the edge of school grounds in Dublin.
Pupils and staff at Scoil Iosagain in Aughavannagh Road, Crumlin, were evacuated after the device was found.
Local sources said the bomb was found by a caretaker just inside the railings of the small school yard close to where young pupils would have been playing on their break.
Labour councillor Michael O'Sullivan said gardai must crack down on suspects in the area. "It's terrible and showed a complete disregard for children's safety," he said.
"It's really amazing nothing worse happened. If you are going to leave a bomb in a school yard you have no idea that it won't hurt any kids."
The Defence Forces bomb squad was called to the school on Monday morning before 10am.
"Students in the school were moved to a safe location during the operation. A cordon was also put in place for public safety," a spokesman said.
The Defence Forces described the device as a viable improvised explosive device (IED).
The explosive was made safe on the school grounds without a controlled explosion and the device was taken to a secure military location for further technical examination and testing. The scene was declared safe at 11.25am.
The device will be handed over to gardai for further investigation.
