I think the accusation against Russia, more specifically Russian intelligence (GRU et all) might be revealing something about our own intelligence agencies using kill quotas (something currently unknown to the Western public), attempting to muddy the waters.
We even had something happen within factions of our own government.
The "deep state" neverDrumpfers were pissed about Trumps Syrian withdrawal and likely incited terror proxies to attack American troops in Manbij.
Manbij, Syria
Manbij is the foreign intelligence capital within Syria

Foreign intelligence agents arrested by Syrian army in Manbij
SYRIA (VOP TODAY NEWS) — According to the Russian news agency Sputnik, intelligence agents from various countries were arrested by the Syrian army in Manbij, northeastern Syria.
The presence of secret agents in this part of Syria testifies to the existence of underlying cells whose mission would be to coordinate the passage of terrorists and agents of foreign countries in Syria, many of which have already been identified and eliminated during the crisis in the country.
Some random fucking redditor even blew the whistle on an upcoming intelligence-sponsored attack on our own troops

US Soldiers will be killed in Syria in the coming weeks.
Hello Everyone, Not sure where else to post this. But the insider word in the intelligence community is that several US Soldiers in Syria will be killed in the coming days or weeks. A small operation in the Manbij area will include IEDs and sniper fire killing several US operators. The ultimate goal is to blame the operation on SAA soldiers from Assads forces. Thus creating public outcry and forcing the US to stay in the area...
The OP elaborated he had intel connections from YPG's:
I actually was YPG fighting against ISIS.
Something similar enough to what OP described happened, so we can conclude his info was likely genuine, which is why he got targeted by the FBI

Erdogan: Terror Attack in Manbij, Syria May Be Aimed to Influence US Withdrawal
Due to the diplomatic backlash this event created, Trump was no longer able to simply withdrawal and needed a new pretext. To get this pretext he used Turkey (US ally, but also funds some Islamist terror groups) to have the greenlight to attack Kurdish Anarchist/YPG terror networks.
This led to the infamous Turkish invasion (and consequential Kurdish elimination of Anarchist rule, returning to Russian/Syrian consolidation of territory) which sparked the Kurds to oust their Anarchist overlords and instead beg Syria to accept them back, while creating potential intel leaks

The retreat from Kurdish areas left a ton of intel in the hands of the Russians
...Yet, with one exception, little has been written on the longer-term (counter-)intelligence implications. Make no mistake: this is an intelligence (and propaganda) gift to the West's adversaries – especially Russia.
...The greatest vulnerability comes from Kurds now forced to seek Syrian and Russian protection, exposing all fighters – but especially elite Kurdish counter-terror units – to pressure of one kind or another.
For five years, these units operated alongside US, UK and French special forces against ISIS, learning much along the way about western tactics, equipment, sources and methods.
Over time, Russian, Iranian, and Syrian intelligence officers will debrief selected Kurdish fighters, while also looking to recruit long-term agents who may be secretly activated when again working with western forces, for example.
Plus there will be defections and information given, I imagine some of them would come across communications from actors like Morell who likely put out hits on Iranian/Russian heads.
This focus (and relative neglect in MSM) on the intelligence value of "elite Kurdish counter-terror units" is extremely important. The name "counter terror units" is virtually the same as our Vietnamese (coincidentally involving Russia as an enemy) "counter terror teams", and the fact the Kurdish ones were coordinating with Western intelligence agencies seems to allude they were Phoenix program inspired, and that we were seeing a repeat of the same oppressive bullshit citing a pretext of "muh terror" to attack civilians. The Phoenix program also had kill quotas.
This revealing our foreign policy as essentially Vietnamese-era ran is a huge vulnerability which will ruin our remaining "humanitarian" credbility for military efforts.
