Gardaí have warned of possible revenge attacks linked to this morning's grenade blast in Dublin.

Over 100 people were moved out of their homes after a hand grenade exploded in Park Terrace in the Coombe area of the city.

A suspect package and a hand grenade pin were subsequently found and the Army Bomb Disposal Team carried out a controlled explosion.

Gardaí say it was fortunate that no one was seriously hurt or killed.

The officer leading the investigation, Supt Thadie Muldoon, said gardaí are following a number of lines of inquiry in relation to the incident.
