A security alert which saw a controlled explosion on a viable device ended after four days on Saturday.
A charity received a call on Wednesday to say that a device had been left at Legavallon Road at Drumsurn, near Dungiven in Co Derry.
Residents were forced to leave their homes before the security operation finally concluded on Saturday morning and all roads were re-opened.
In a statement to a Derry newspaper, republican group Óglaigh na hÉireann claimed it planted a bomb in the area five weeks ago.
It also claimed responsibility for a mortar and gun attack in the Currynierin area of Derry earlier this year.
It is believed British soldiers who took part in training exercises in the Drumsurn area may have been the target.
Meanwhile, in Co Antrim, a security alert in the British Road area of Crumlin, also on Saturday, was declared as 'nothing untoward'.
There were no road closures or evacuations during the Crumlin alert.
