Children from a number of north Belfast primary schools could have been killed or maimed after a suspected booby trap bomb fell from a car in a heavily populated area.
There has been widespread condemnation after the device was discovered on Monday at Ballymagarry Lane near Springhill primary school and three nearby schools.
Police said yesterday that they believe the device may have been an "under-car booby trap designed which was to kill and maim".
Two controlled explosions were carried out during a security alert which saw hundreds of households evacuated and roads closed.
It is believed that dissident republicans were behind the incident.
The security alert resulted in the closure of Ballymagarry Lane, the only access route to over 250 houses at Lyndhurst Meadows and Heath Lodge.
During the alert Belfast City Council established an emergency rest centre at Ballygomartin Presbyterian Church.
North Belfast assembly members William Humphrey and Alban Maginness have condemned those responsible.
