1. Jihadists in #Syria are reporting that Abu Saloh, the founder and former emir of the Uzbek group Katibat al Tawhid wal Jihad (now part of HTS), was arrested by HTS' internal security yesterday after he reportedly defected to Jabhat Ansar al Din. 
2. Abu Saloh left his position as emir of KTJ sometime last year, opting for more behind the scenes work and preaching. He founded the group in late 2014. Which I covered back in the day: thelineofsteel.weebly.com/news/katibat-a…
3. KTJ was originally part of al Qaeda's Jabhat al Nusrah before splitting to be its own group. It then rejoined in Sept. 2015 and is now part of HTS - though it retains some autonomy in terms of media output thelineofsteel.weebly.com/news/an-update…; longwarjournal.org/archives/2015/…
4. Jabhat Ansar al Din (JaD), which has existed since 2014, is currently part of the Hurras al Din-led "So Be Steadfast" operations room. JaD has also been more within the al Qaeda fold in #Syria, where Abu Saloh originated.
5. Jihadists are further alleging that the issues surrounding Abu Saloh are old and have been settled but have been reinstituted following his defection to JaD.
6. JaD has reportedly attempted to settle these disputes behind the scenes with KTJ and its new emir (whom the UN notes is a veteran of the AQ-linked Islamic Jihad Union), but it seems HTS proper is now taking matters into its own hands if this is true.
