Police have arrested five people during Britain's first anti-Islam Pegida rally in Newcastle's city centre.
Northumbria Police said 375 people were on the Pegida rally while 2,000 joined a rival demonstration called 'Newcastle Unites'.
There was a brief scuffle involving members of far-right groups which temporarily damaged Pegida's PA system, a steward said, but there was no outbreak of major trouble.
Police said the arrests were for isolated incidents and both events passed off smoothly.
It was unclear which sides the five arrested men were from, and their alleged offences ranged from assault, to being drunk and disorderly and breach of the peace.
Newcastle Chief Superintendent Laura Young said: "Both demonstrations passed without any problems and I'd like to thank people in Newcastle for their cooperation and support throughout.
"The vast majority of those that took part in today's events were peaceful and both groups stuck to their agreed times, routes and plans."
Avon and Somerset Police have decided not to release details on the suspects arrested in the case of missing Bristol teenager Becky Watts.
ITV News Correspondent Rupert Evelyn reports:
BBC political editor Nick Robinson is being treated for a lung tumour but hopes to be back at work in time to cover the general election campaign in May, his agent said.
The 51-year-old journalist needs an operation to remove a bronchial carcinoid tumour from his lung.
In a statement, his agent said Mr Robinson, who is married with three children, would be "taking a short time off work over the next few weeks".
She added: "His doctors are aiming to get him back at work in plenty of time to cover the election campaign proper.
"He and his family have asked that they now have the space and privacy he needs in order to rest and recover fully before returning to work."
On its website Cancer Research UK says carcinoid tumours are rare and tend to be slow growing, sometimes not causing any symptoms for several years.
Around a quarter start in the lung and typically do not spread to other parts of the body.
Scotland were left facing their fourth wooden spoon in 11 years after a late collapse handed Italy a 22-19 RBS 6 Nations win at Murrayfield.
Mark Bennett's intercept try and 11 points from skipper Greig Laidlaw's boot looked to have put the hosts in command early on.
But scores from Joshua Furno and Giovanbattista Venditti, plus five points from kicker Kelly Haimona, allowed the Italians back into the contest just before the break.
Laidlaw added another penalty after the restart, but his side could not hold off a late surge from the Azzurri and left referee George Clancy no option but to hand the Italians a last-gasp penalty try, converted by Tommy Allan.

She left home on February 19 with her phone, laptop and tablet computer but did not inform friends or family where she was going, or take extra clothes. Avon and Somerset Police have been searching for the teenager, described as shy, since she was reported missing by her family at 4pm on February 20.

Police previously said there was "nothing to suggest" that Becky had come to harm, despite fears from Becky's father that she had been attacked.
