Boko Haram urges Somali's Al-Shabaab terror group to join Islamic State

In a video posted on Twitter on Wednesday, October 14, Boko Haram extremists urged Somalia's Al-Shabaab terror group to join them in pledging allegiance to the leader of the Islamic State group, and thus abandon al-Qaida.

In the video, an unidentified armed Boko Haram fighter tells Al-Shabaab fighters that uniting "is of greater benefit to the struggle on the path of Islam" and will "help in defeating the infidels of the world." The appeal is part of a wider courting of Al-Shabab. Similar messages came nearly two weeks ago from militant extremists in Iraq,Sinai, Syria, and Yemen.
