This is no surprise to me, and though silenced nontheless breaking. These two links are the only one Google comes up with.
Breaking, because the capacity of Professor Philip Alston, United Nations Special Rapporteur on extrajudicial, summary or arbitrary executions,
reporting it makes it now as official as can be. Despite that, NO major news outlet --except a lib one like WP-- have (yet) found it worth
reporting.
We have heard about death squads in about every war America has been involved, but it has always been by proxy of local melitias or undercover agents.
That official intel forces now operates makes it in double sense breaking. Identification of nationality of the services involved has not been made,
but it doesn't take much guessing as to who(m) it/they might be.
As many as 200 civilians have been killed in the first four months of this year, often in joint operations with Afghan security forces.
Statements of Philip Alston at the press conference:

I have spoken with a large number of people in relation to the operation of foreign intelligence units. I don't want to name them, but I can
say they are at the most senior levels of most of the relevant places. It is clear that there are certain units operating in certain provinces; the
names are well known to those involved, and these forces operate with what appears to be impunity.

Lastly, my report looks at killings by the Taliban and other anti-government elements. The estimate is that in the past four months alone, over 300
people – civilians -- have been killed. To the extent that those targeted are legitimate military targets, the Taliban is not violating
international law. The disaster, however, is that a huge proportion, probably 95 per cent, probably more, of those killed are innocent Afghan
civilians.
i.e. the 200 killed by joint security/intelligence forces are illegal killings.
My guess is that these extrajudicial killings have nothing to do with fighting Taliban (admitted by Afghan authorities) but with the "War on Drugs,"
has to do with controling the market.
