I want to flesh out my own witness of this.
I was walking uptown towards Penn Station on Varick. I saw a taxi parked to the curb, Muslim driver, with a mesh skull cap parked to the curb, door open next to a food cart. Crowd was around 5 or so and listening in Arabic and every so often they would say Allah Akbar! and smile and some would shake hands or embrace at some news. I saw this. It was near the US Veterans affairs building. At the time I just took it as them maybe praying or what not but then realized it was them exalting in an Islamic victory.
