British police and security services are also upset that the name of British bomber Salman Abedi was apparently leaked by USA officials and published while police in Britain were withholding the name for operational security.
Meanwhile, the investigation into the blast widened.
Authorities chased possible links between Abedi and militants in Manchester, elsewhere in Europe, and in North Africa and the Middle East.
Authorities are also looking into Abedi's relationships with several known militants, including Raphael Hostey, an ISIS recruiter who was killed in a drone strike in Syria previous year.
A group of Gaddafi dissidents, who were members of the outlawed Libyan Islamic Fighting Group (LIFG), lived within close proximity to Abedi in Whalley Range.
An emerging portrait of the bomber remained complicated by competing assessments over whether Abedi held views that had sparked concern before the bombing.
France's interior minister said Wednesday that Abedi had "most likely" travelled to Syria, a stronghold of the Islamic State in Iraq and Syria (ISIS).
