Elon Musk called out UK Prime Minister Keir Starmer in a post on his platform X on Tuesday after Starmer said a "standing army" would be put in place across the country to quell protests against mass migration. British police had arrested hundreds of protesters over the weekend, many of whom were targeting migrant centers and mosques.

In response to the protests, however, "Muslim patrol" vigilante groups were formed. Participants took to the streets in masks, many wielding weapons, to hunt down and attack "white right-wingers," as Post Millennial Senior Editor Andy Ngo reports.

Ngo, who has been documenting the riots at length, reported in one instance in West Midlands that the "Muslim rioters attacked journalists and slashed up the vehicle of a Sky News team," adding that, the West Midlands Police "said they had "well-rehearsed plans in place" to deal with right-wing protests. "But they did not show up to the group of around 300 Muslims who mobilized for a direct action."

In response, Musk took aim at Starmer, stating "Why aren't all communities protected in Britain?" In a follow-up post, he hashtagged "#TwoTierKeir."

Protests and riots initially broke out across the UK in response to the fatal stabbing of three young school girls last week carried out by the son of African migrants, causing widespread clashes with UK police. Starmer has threatened that "far-right" protesters would "regret" their role in the protests.
