A video released by an Al-Qaeda affiliate is calling for attacks on malls in the United States and other parts of the western world.

Al-Shabaab release the video Saturday citing three malls:  The Mall of America in Bloomington, Minnesota; West Edmonton Mall in Alberta, Canada; Oxford Street shopping area in London, England.

The terror group, which was behind the deadly Westgate Mall attack in Nairobi, Kenya in 2013, showed images of that assault at the start of the clip before issuing a call.

“If just a handful of mujahedeen fighters could bring Kenya to a complete standstill for nearly a week then imagine what a dedicated mujahedeen in the West could do to the American or Jewish-owned shopping centers across the world?” he asks. “What if such an attack were to occur in the Mall of America in Minnesota? Or the West Edmonton Mall in Canada? Or in London’s Oxford Street?”

“What would be the implications of such an attack? One could only imagine. And all it takes is a man with firm determination,” he continues. “So hurry up, hasten towards Heaven and do not hesitate.”

The Mall of America announced they have increased security in response to the video.  The Department of Homeland Security said they are aware of the video and they’re taking steps to analyze the footage.

Jeh Johnson, head of Homeland Security, said people shopping need to be careful.

“If anyone is planning to go to the Mall of America today, they’ve got to be particularly careful,” he said. “There will be enhanced security there, but public vigilance, public awareness and public caution in situations like this is particularly important, and it’s the environment we’re in, frankly.”
