Twelve years of trying: bombs; infiltrations; the occasional political murder attempt -- not a success... until now.
In the Northern Ireland of today, a land in the main at peace, two British Army Engineers were killed, two others of their fellows wounded, as were two civilians in a "guns-only" attack run by the Real IRA (one of the remaining "dissident" Provo groups still under arms). It wasn't against deployed forces: it was from a commandeered taxi driven close to a basing area.
The young soldiers killed and wounded were receiving a pizza delivery at the gate of the base at the time of the attack.
Update: more details here.
The statement from Sir Hugh Orde regarding a request for SRR assets to be deployed is likely not of direct relevance to this attack. The knowledge that attack-risk was rising may have influenced his decision to ask for such support, however.
The SRR is the modern-day incarnation of JCU (NI), 14 Int Co. Royal Army that was of great service to the Kingdom during the 'Troubles. It is now a part of United Kingdom Special Forces.
