World Net Daily has the story:

JERUSALEM – A U.S. jihadi website has issued a series of videos targeting the New York headquarters of Chabad, a Jewish outreach movement, just two months after the group was rocked by a deadly terrorist attack in Mumbai, India.

The videos also ask viewers to "give the Islamic message" to Yeshiva University, a Manhattan-based Jewish college, as well as "Jewish Federation buildings all over the U.S." in response to the institutions' purported funding for Israel amid its recent offensive against Hamas in the Gaza Strip.

The Islamic threats already resulted in a New York Police Department investigation and a beefed-up police presence outside the Chabad headquarters, WND has learned.

"When an atrocity is done like what was done in Gaza, indiscriminately killing women and children, we know who the source is," stated Yousef Al-Khattab, the CEO of RevolutionMuslim.com in a video address posted on the website.

"These are definitely the sources," Khattab stated, citing Chabad and the other Jewish institutions.

"We think it's imperative to hold these people responsible, speak in front of their homes, give them the Islamic message. Leave them the message of Islam. That's not a threat, that's what it is," Khattab said in the video.
