London, August 10 (RHC)-- Britain is facing a national crisis in the face of the worst rioting in 13 years.  Violence by far-right groups was sparked by the fatal stabbing of three young girls in Southport last week and stoked by misinformation on social media.

A tense few hours in this part of London ahead of a potential anti-immigrant, anti-Muslim, far-right attack; their target, a legal center in this public building that supports refugees.

One anti-racist protester said: "There is fear in the air, shops and offices have closed early.  There's a heavy police presence but before long anti racist protesters assemble to protect the building, their numbers swelling quickly.  I've heard of multiple points being targeted tonight by the far right.  And I think it's my duty to come here as a migrant myself but also as a professional and stand by refugees."
