kakashi caught them, kakashi barely countered though, it was kurenai who was like "hand seals so fast, i couldnt even see them" and itachi made that move even better by make a movement with the shuriken in his hands, dragging your attention to that area making you think he'll throw them but instead he attacked with a jutsu that took zabuzza and kakashi like 5 min in the wave country arc.
