(CNN) -- Al Qaeda leader Ayman al-Zawahiri is calling on Muslims to kidnap Westerners, citing the success in the abduction of American aid worker Warren Weinstein in Pakistan. In a two-part, more than two-hour video posted on jihadist websites, al-Zawahiri called for the abductions as part of a vow not to "spare any efforts" to free Sheikh Omar Abdel-Rahman, the mastermind behind the 1993 World Trade Center bombing. "God the great and almighty granted us success to capture the Jewish American Warren Weinstein," al-Zawahiri said in the video posted Wednesday, according to the terror monitoring group SITE Intelligence. "We are seeking, by the help of God, to capture others and to incite Muslims to capture the citizens of the countries that are fighting Muslims in order to release our captives."Ayman al-Zawahiri calls for the kidnapping of WesternersAl Qaeda's leader made the call in a video posted on jihadist websitesAl-Zawahiri cites the kidnapping of Warren Weinstein as an example
