A Co Down raised terror suspect on the run from international police has lashed out at a fellow fanatic on Twitter.
Banbridge-raised Samantha Lewthwaite - who has been dubbed the White Widow - called a terror chief "an irritating prat" on the social media site.
The Sun newspaper reported her target was high-profile fugitive Omar Hammadi - who has a £3.3million price on his head.
Born to a Northern Irish mother and soldier father from Britain, Samantha Lewthwaite spent her early years in her home in the Whyte Acres estate in Banbridge.
But Samantha's conversion to Islam in her late teens unleashed a series of events which brought together bomb plots in London and Kenya -- and has seen the mother of three on the run for the last 13 months.
Samantha's mother, Christine, married British soldier Andy Lewthwaite in the 1970s.
They settled in Christine's native Banbridge, where their daughter, Samantha, spent part of her childhood, and they stayed until the marriage broke down.
Samantha was 17 when she converted to Islam, changing her name to Sherafiyah.
She married Germaine Lindsay, who would later detonate a bomb in London's King's Cross Tube Station killing 26 people and himself, in July 2005.
Lewthwaite condemned the 7/7 bombings, but is now suspected of involvement in a planned bombing campaign in east Africa.
The 29 year-old is suspected of being part of a cell affiliated to al-Shabaab, an al-Qaida-linked group in Somalia, which planned to mount attacks on Kenyan port city Mombasa in December 2011.
In June last year, Kenyan police reported a sighting of a woman matching Lewthwaite's description near Mombasa's Jericho bar, shortly before a grenade attack on June 24.
Three people were killed and 25 injured as crowds watched England play Italy in the Euro 2012 championship.
Lewthwaite is currently thought to be hiding in Tanzania or Somalia, after more than a year on the run with her children.
