Surprise (and just in time): In parts of this battle-torn country, a second civil war has begun

From The Wall Street Journal:

In parts of this battle-torn country, a second civil war has begun.
In the north and east bordering Turkey and Iraq, a stretch of Syria in rebel hands has split into competing fiefs. In some places, Islamist extremists with agendas that extend far beyond Syria are pushing aside the rebel battalions that started the insurgency against Bashar al-Assad's regime in 2011.

The resulting chaos has fragmented the rebel fight and created a playground for al Qaeda just as a U.S. debate heats up over how deeply to get involved.
