A Real IRA gunman has taken to Facebook to warn Queen Elizabeth that she will be assassinated in Dublin later this month.



Glen Mallon, a convicted Republican, has warned the British monarch that ‘there’s a rocket coming for you’ on his social network site.



The 38-year-old Mallon was once in charge of procuring arms for the Real IRA.



He was jailed for five years in 2006 when he was caught in possession of a pump action rifle and ammunition by Irish police.



Mallon was also charged with membership of an illegal organization styling itself as the Irish Republican Army.



The Sunday World reports that Mallon has sent a chilling message to the queen ahead of her Irish visit.



Writing on his Facebook page, Mallon warns: “She’s coming prepared to Dublin, yeah. But look in your mirror there’s a rocket coming for ye, hehehe.”



The latest Mallon comments are being monitored by Dublin police.
