Rival protesters clash in Glasgow amid migration tensions (VIDEOS)

On Saturday, the NGO Stand Up to Racism held a rally in downtown Glasgow, with organizers calling on supporters to “reclaim the streets from the far right.” Participants carried Scottish and Palestinian flags and chanted, “Refugees are welcome here,” according to The Herald.

Around 70 counterprotesters arrived at the event, many dressed in black and wearing balaclavas.

As police sought to keep the rival groups apart, some anti-immigration demonstrators pushed against barriers and shoved officers. Some of their opponents also pushed police while attempting to break through the separation line.

Police Scotland said one man was arrested for threatening an officer, while another officer was struck by an egg thrown during the unrest.

“A number of reported hate crimes will now be investigated,” a police spokesperson said.

An anti-racism demonstration also took place in Belfast, Northern Ireland to denounce the riots that followed a stabbing on Monday. A Sudanese asylum seeker has been charged with attacking a man in the street and allegedly blinding him in one eye.

Another high-profile incident occurred on Friday in Brierfield, England, where a man stabbed a 17-year-old girl in the middle of a street, causing non-life-threatening injuries. Police described the suspect as a British man of Pakistani descent.

The recent attacks have reignited debates about migration and what right-wing politicians and activists describe as two-tier policing. They argue that the incidents highlight the government’s inability to adequately address crimes committed by foreigners and other offenders.

Prominent anti-immigration activist Tommy Robinson said he was detained for several hours at Heathrow Airport on Saturday under anti-terrorism legislation and had his phone seized by police.

According to Sky News, Robinson is scheduled to take part in a debate at the Oxford Union next week on whether the West is “right to be suspicious of Islam.”
