Northumbria Police said around 200 people gathered at the EDL event and at a counter-demonstration in Millfield, Sunderland, when disorder broke.
Witnesses said officers told residents to stay in their homes while they tried to calm the crowd.
Asst Chief Cons Steve Ashman said he was "disappointed" as both sides had said that the event would be peaceful.
He said: "Despite assurances from both sides that this would be good-natured and respectful of the local communities, a number of those attending engaged in disorder.
"A police presence remains in the area to reassure communities.
"It is disappointing that a protest that was planned as peaceful has resulted in arrests.
"We will not tolerate any sort of disorder and those seen to be committing such offences will be arrested."
