| Threats After UNOPS
Corruption Leaked to Inner City
Press Amid Demand for UN Records

GATE, Sept 13
â
How corrupt is today's UN
under lame duck Antonio
Guterres? Well, even those few
UN officials bounced for
corruption are simply
re-hired, and no one answers
why. Inner City Press
published this, from UNOPS
whistleblowers: Dear Matthew
Russell Lee and Inner City
Press Editorial Team, Despite reforms
announced after the S3i
scandal, the root causes
remain unchanged. Key
facts: UNOPSâ internal
accountability bodies (IAIG
and the Ethics Office)
continue to shield senior
officials and silence
whistleblowers. Abdoul Dieng
(Director, IAIG) and Berkan
Manaigo-Vekil (Director,
Ethics Office) must be removed
and independently
investigated. Abdoul
Dieng played a central role in
the cover-up of the S3i
scandal and is now engaged in
concealing misconduct in the
UNOPS Nicaragua scandal and
the DUNDEX case. Of 91
retaliation complaints in
UNOPS history, only 2 were
ever upheld, both nearly a
decade ago. None of the 34
cases filed between 2022â2024
were recognized. The trusted
NAVEX whistleblowing platform
was scrapped and replaced by a
weak in-house tool that lacks
basic safeguards. The abusive
use of ICA contracts persists
globally, most recently
exposed through the mass
dismissals in Geneva and at
the Stop TB Partnership, where
staff were treated as
disposable. Our message is
simple: S3i is not over. The
same structural failures that
enabled it still exist
today. We have submitted
a detailed letter to the
Executive Board of UNOPS
[Inner City Press has a copy,
as well as the distribution
list] Now on September
13, 2026, the day after Inner
City Press demanded
records about UNOPS
Vitaly Vanshelboim from the
UNDT and UNAT under their
rules, this from the
whistleblowers: Dear Inner City
Press, We are writing as
the UNOPS Nicaragua Collective
to bring to your attention a
serious accountability
situation unfolding in UNOPS
Nicaragua and to request your
continued scrutiny of what may
be a broader issue affecting
UNOPS personnel across
different regions. We
appreciate your coverage of
UNOPS colleagues seeking
accountability worldwide,
including the situation
involving Nathalie Angibeau in
Africa. What we are
experiencing in Nicaragua,
together with recent
developments in Mozambique and
concerns emerging elsewhere,
raises an important question:
whether UNOPSâs internal
oversight system is providing
personnel with genuinely
independent investigation, due
process, protection and
effective recourse. In
Nicaragua, several former
personnel continue to have
serious complaints unresolved,
with limited or no effective
internal recourse. We possess
documentary evidence that
raises serious questions about
IAIGâs handling of allegations
involving fraud, financial
mismanagement, retaliation,
harassment and abuse,
including IAIG-2025-172 and
IAIG-2024-249. We are
not asking anyone to accept
our allegations as established
facts. We are asking for an
independent body willing to
examine the evidence. We
have therefore formally
requested the UNOPS Executive
Board to commission an
independent investigation into
the actions of IAIG Director
Abdoul Dieng concerning the
Nicaragua cases and an
independent review of IAIGâs
handling of the relevant
complaints, investigations,
findings and decisions. We are
also requesting safeguards for
complainants and a secure
mechanism through which our
documentary evidence can be
submitted directly to
independent reviewers.
We previously sought an
independent review through
representatives of the UNOPS
Global Personnel Association
Forum and subsequently pursued
external oversight through
OIOS complaint OIOS-0222-26.
That matter was closed without
the Collective having an
opportunity to present and
explain the body of evidence
underlying our
allegations. Our
concerns intensified following
a communication from Mr. Dieng
on 28 August 2025 (see
attachment) in which, after
referring to alleged
defamatory statements and
breaches of UN confidentiality
rules, he stated that he
intended to pursue the matter
through means available under
UN rules, international law
and national law enforcement,
expressly in his individual
capacity. Against the
background of unresolved
complaints involving the
office he directs, members of
the Collective experienced
this communication as
intimidating and
threatening. The
institutional problem is
simple: when serious concerns
are raised about the conduct
of an oversight function, that
same function cannot credibly
be the final authority
deciding whether its own
actions warrant
investigation. This is
also why we believe Nicaragua
should be viewed alongside
developments elsewhere in
UNOPS. In Mozambique, 26 UNOPS
personnel have reportedly been
referred in connection with
allegations of collusion and
financial mismanagement,
alongside proceedings
involving 15 contractors. The
circumstances are different,
as are those involving
Nathalie Angibeau, and we make
no presumption regarding
anyoneâs guilt or innocence.
But across these cases,
similar questions are emerging
about investigation,
attribution of responsibility,
due process, protection and
access to effective
recourse. We have the
evidence concerning Nicaragua.
We are prepared to provide it
confidentially and explain it
document by document. What we
need is an independent and
credible mechanism willing to
examine it.
Sincerely, UNOPS
Nicaragua Collective" We'll have
more on this- and on the
requested records, and Inner
City Press' application to
enter the UN to get to the
bottom of this corruption, and
more, pending since July 25,
2026, here.
