An incendiary bomb has been removed by army technical officers in County Derry, the Police Service of Northern Ireland has confirmed.
The security alert occurred in Maghera in the early hours of Friday morning, the PSNI said.
The bomb, which was put on the ground under a van in the Willow Glynn area, partially exploded at around 3am.
The device was reported when it was discovered by the vehicle's owner at 8am, police said.
A PSNI spokesman said they believe the device was left in the area sometime between midnight and 3am.
Local councillor Kate Lagan said she was shocked by the blast: "This is a quiet estate, full of young families and children on their bicycles and this device could have caused tragic consequences.
"I have no idea why it was left here, but it doesn't matter who it was meant for, a person could now be dead.
"I think it's ridiculous and it makes me very angry."
The technical officers have examined the bomb and removed it for further examination.
