The current al-Qaida terrorist plot against U.S. and Western targets is a direct result of U.S.-supported efforts currently underway to purge al-Qaida affiliates from the ranks of the Syrian rebels, according to informed Middle Eastern security sources.
The sources have specific knowledge of the terrorist threat that has prompted a worldwide travel alert and the closure of 22 U.S. embassies.
Those sources said the U.S. has been working with Saudi Arabia, Qatar, the United Arab Emirates and other Gulf states to support a U.S.-armed Free Syria Army effort to cleanse al-Qaida affiliates from among the rebel ranks, including al-Nusra and other groups.
For months now the U.S. has reportedly been providing lethal support to the Syrian rebels amid widespread fears the Western weapons could fall into the hands of al-Qaida organizations known to work alongside the Free Syria Army.
