"'Hamas has been very well prepared for this and has created professional systems to get their message out,' said Josh Lipowsky, a senior research analyst at the Counter Extremism Project, an advocacy group in Washington that tracks online extremism.

Hamas’ warning of execution broadcasts suggests the group is pushing for a more accelerated style of terror propaganda, Lipowsky said.

'The value is to demoralize,' he said. 'It is a form of emotional warfare. It is Hamas looking to break the spirits of Israelis and the global Jewish community.'"
