Muslims in full attire in grocery store anchorage Alaska

This was actually a first for me and my kids (and from the gaping mouths of other customers it was theirs as well). We were doing our normal shopping and a large group of Muslims (2 men and about 15 women all dressed in the traditional long dress things and head coverings gathered in produce blocking an entire aisle while one of the men also dressed in traditional clothing spoke very loudly (yelling IMO)in what I guess was Arabic.

They were all black and walked in a big group when they left produce not allowing anyone room to walk, others stepped aside. The women stared daggers at other women, I just stared back at them. I've seen people with headscarves and normal clothing, but nothing like this.

None of them had coats or warm clothing on either, my son wondered if they were from Syria. I hope we don't have this to look forward to now.
