Kofi Annan's Syrian peace plan has been blown out of the water

While Syria's opposition is unlikely to prevail unaided, extremists seem intent on driving the conflict's deep sectarianism

The two suicide car bombs in Damascus on 10 May were an alarming development. Before last December suicide bombs were unheard of in Syria. Now there have been 10 such attacks, becoming increasingly deadly – 55 died in the latest atrocity; and on 11 May another attack was thwarted in Aleppo, Syria's largest city, where a suicide bomber in a carwash killed five on 5 May.
Damascus and Aleppo are home to Syria's business and professional classes, who have not, in general, participated in the uprising, tending to remain loyal to the Assad regime. The suicide bombs have targeted government buildings, the security services and the ruling Ba'ath party's headquarters. While many civilians died in Thursday's blasts, significant numbers of security personnel have also been killed.
