Danny Welbeck netted a stoppage-time equaliser as the Gunners salvaged a point from yesterday's Premier League clash in London.
However, Hull's first goal was shrouded in controversy after Mohamed Diame appeared to pull back Flamini en route to cancelling out Alexis Sanchez's opener.
"I'm very frustrated. First of all with the referee's decision for the first goal. It was clear to everyone it was a foul," the Frenchman told the club's official website.
"I was in front of the player and he pulled me back so it was a very poor decision by the referee. I respect the referee and his decision but he was the only one not to see the foul."
The two dropped points have left Arsenal sixth in the Premier League table, 11 points adrift of leaders Chelsea.
