A blast bomb has been defused in the garden of a Co Tyrone house today.
The device was made safe by the British army following an overnight security operation at the property on the Strahulter Road near Newtownstewart.
Police said it had the potential to kill, cause serious injury or damage to property. The area had been sealed off after an anonymous telephone warning of a device having been left.
Dissident republicans were believed to be responsible for what was one of three attacks launched yesterday. In Strabane, Co Tyrone. the security forces were examining a "viable device" found at a pub car park at Cloughcor.
Elsewhere, a security operation was continuing around the police station in Craigavon, Co Armagh, after bomb remains and a mortar tube were discovered.
Police believe a mortar fired at the police station in the Brownlow area of the town missed its target and landed at the rear of the local health centre across the road.
It was the first such attack in some time and an escalation of a dissident campaign that has caused more than £30 million in damage in a series of fire bomb attacks on commercial premises in Belfast and Newry, Co Down, during the past year.
