Gardaí are investigating an explosion at a house in Limerick early this morning.
An incendiary device was planted at a house on the south-side of the city.
It exploded at around 1am after being attached to a window of a house in Raheen Square, Ballinacurra Weston.
The family inside the house at the time of the explosion, including children, escaped injury.
It is believed the house involved as also targeted two nights ago.
Gardaí say this morning's incident may be linked to ongoing violence between families in the Ballinacurra Weston, Hyde Road area of the city.
