Cologne attackers were of migrant origin - minister per BBC News through gritted teeth

The BBC report through very gritted teeth that:

'The men suspected of attacking women in Cologne on New Year's Eve were "almost exclusively" from a migration background, mainly North African and Arab, an official report says.'

But the BBC being the BBC, they have to try and lay the blame elsewhere:

'Cologne police also made "serious mistakes" in not calling reinforcements and the way they informed the public.
 

More than 500 criminal complaints were filed, 40% alleging sexual assault.'

And the BBC's main worry is the possibility of retaliatory attacks:

'Apparent retaliatory attacks in Cologne on Sunday were condemned by the government as inexcusable.'
