Saturday brought to the world the Merger from Hell: the Nigerian Islamic terror group Boko Haram has pledged their allegiance to the Islamic State (ISIS), a move that BBC reporter Jim Muir says “makes them look more like a global franchise.” The pledge was attributed to Abubakar Shekau, the leader of Boko Haram. US intelligence estimates that ISIS may be gaining between 4,000 – 6,000 fighters.

Boko Haram took to Twitter to announce their news.

Not bad for a JV team. 

Boko Haram is only the latest fish to be hauled in by ISIS. In addition to terror groups from northern Africa and the Arabian peninsula, a Taliban group from Pakistan pledged its allegiance to ISIS. At the end of 2014, a senior jihadi leader from Dagestan pledged his allegiance to the head of ISIS, Abu Bakr al-Baghdadi.

Boko Haram terrorists have made a name for themselves in Nigeria by kidnapping civilians, executing hostages, and destroying villages. They leave in their wake dead inhabitants and decimated towns such as Baga:

The Islamic State has also been making headlines in terms of destruction, only it’s been adding historical sites and art treasures from Iraq to its conquests. Their most recent demolition project was the 2,000-year-old city of Hatra, 68 miles southwest of Mosul, which earlier saw destruction of their library and artifacts from their museum.
