Riots erupted Monday night in Rinkeby, a heavily immigrant Stockholm suburb, as looters set cars on fire and threw rocks at cops, injuring one police officer, according to Swedish officials.

The violence began around 8 p.m. when officers arrested a suspect on drug charges at an underground station. Soon a crowd gathered, hurling rocks and other objects at officers and prompting one cop to fire his gun "in a situation that demanded he use his firearm," police spokesman Lars Bystrom said. No one, however, was found injured from a gunshot wound at the scene nor at any hospitals.

The riots came just days after President Trump was mocked during a Saturday campaign rally for mentioning Sweden among a list of European targets of terror for taking in refugees. Trump later said, "You look at what's happening last night in Sweden," information he received after watching a Fox News report on the country's refugee crime crisis that aired Friday evening.

"Sweden. They took in large numbers [of refugees]," Trump added at the Florida rally. "They're having problems like they never thought possible."

Sweden's official Twitter account - which is operated by a different user each week - tweeted at Trump on Monday morning: "Hey Don, this is @Sweden speaking! It's nice of you to care, really, but don't fall for the hype. Facts: We're OK!"

Hours later, the Rinkeby riots began, with a second wave starting around 10:30 p.m. Seven or eight cars were set on fire and many stores saw looting.

No arrests were made, but there were reports filed on three violent acts, violence against a police officer, two assaults, vandalism, and aggravated thefts, authorities said.

The country's prime minister, Stefan Lofven, said Monday, "Yes, we have challenges like all other countries. There's no doubt. We have a situation in the world where 65 million people had to flee their countries last year, the year before that. 65 million. So that's a war for us together." He also said Sweden was investing more in housing, technology, and its welfare system.
