Most likely yes since there's no interceptor missiles visible, but the streaks of light are still just glare from a dirty lens. The first two projectiles were killed by two separate lasers because it takes a bit for a laser to heat its target up.
This is just somebody's grimy phone camera seeing streaks of light around the bright flashes. You get these when you wipe your lens carelessly with linear movements. It's a funny coincidence that the two flashes happen to allign in the direction of these streaks.
You can see the same effect in the bottom left corner of the screen when the view briefly pans left, around what might be an off screen streetlight.
Could well be Iron beam (especially since we see no interceptor missiles around), but there's two of them here because one laser can't take out two targets at the same time, and the streaks of light are not from the lasers.
