Mayor of Jerusalem Nir Barkat stopped a terrorist, who had seconds earlier committed a stabbing in Tzahal Square. Barkat – an ex IDF paratrooper – saw the incident, got out of his car and when his bodyguard convinced the attacker to drop his knife, Barkat wrestled him to the ground. http://www.timesofisrael.com/watch-jerusalem-mayor-pins-down-terrorist/
