Ban Ki-Moon: Wave of violence in Palestine bred from decades of jewish occupation

Sicarii is a term applied, in the decades immediately preceding the destruction of Jerusalem in 70 CE, to an extremist splinter group of the Jewish Zealots, who attempted to expel the Romans and their partisans from the Roman province of Judea. The Sicarii carried sicae, or small daggers, concealed in their cloaks, hence their name. At public gatherings, they pulled out these daggers to attack Romans or Roman sympathizers, blending into the crowd after the deed to escape detection.

Judas Iscariot, one of the Twelve Apostles of Jesus according to the New Testament, was believed to be a sicarius.
