The second senior EU official confirmed that.
A third source, also an EU official, said the Commission was "cooperating actively with WFP to resolve systemic defects" but said no aid was suspended at this stage.
Last year, it contributed more than half of the $2.2 billion of funding that went to the humanitarian response there.
The U.N. report did not attempt to quantify the amount of aid that was diverted but said its findings "suggest that post-delivery aid diversion in Somalia is widespread and systemic".
In all, investigators collected data from 55 IDP sites in Somalia and found aid diversion in all of them, the report said.
