A man was taken to hospital this morning after a viable device exploded outside a house in Co Meath.
Gardaí are investigating the incident which occurred at 8am at a house in Beechgrove, Navan.
The 48-year-old man opened the door of the property and the device subsequently exploded.
The man sustained minor cuts and was taken to Our Lady of Lourdes hospital in Drogheda, Co Louth for treatment.
A Garda spokesman said there was slight damage to the property after the explosion.
The scene was preserved for an examination by a Garda technical team. An Army bomb disposal team attended the scene.
The motive behind the attack is under investigation.

The scene was made safe, without requiring a controlled explosion, at about 1am and the device was removed for further examination.
