President Barack Obama's administration will seek a significant increase in funding for the fight against Islamic State as part of its 2017 defence budget request, US officials say.
The fiscal year 2017 Pentagon budget will call for more than $US7 billion ($A9.86 billion) for the fight against Islamic State, a roughly 35 per cent increase compared with the previous year's request to Congress, the officials said, speaking on condition of anonymity.
