1. 4 Israelis Dead After Attackers Storm Jerusalem Synagogue

Palestinian assailants wielding knives and axes forged an attack on a synagogue in Jerusalem today, with at least four Israelis dead and two attackers killed by police, a spokesman with Israel Police said.

The attack happened in Har Nof, an Orthodox Jewish neighborhood with a population of 20,000 residents.

2. FBI Warns Ferguson Decision ‘Will Likely’ Lead to Violence By Extremists Protesters

As the nation waits to hear whether a Missouri police officer will face charges for killing unarmed teenager Michael Brown in Ferguson, Mo., the FBI is warning law enforcement agencies across the country that the decision “will likely” lead some extremist protesters to threaten and even attack police officers or federal agents.

Peaceful protesters could be caught in the middle, and electrical facilities or water treatment plants could also become targets. In addition, so-called “hacktivists” like the group “Anonymous” could try to launch cyber-attacks against authorities.

“The announcement of the grand jury’s decision … will likely be exploited by some individuals to justify threats and attacks against law enforcement and critical infrastructure,” the FBI says in an intelligence bulletin issued in recent days. “This also poses a threat to those civilians engaged in lawful or otherwise constitutionally protected activities.”
