A BBC team has joined an RAF reconnaissance mission over Iraq to see how British Tornado aircraft are helping to plot Islamic State (IS) positions on the ground.
The RAF has already been involved in making aid drops to people fleeing IS, while the US has been carrying out airstrikes against the fighters.
The UK has said it would "consider favourably" any request for arms from the Kurds in their battle with extremists in Iraq.
