US stock futures fell on Thursday premarket after Iran's supreme leader issued a directive that the country's near-weapons-grade uranium should not be sent abroad.

Oil rose on the news, with brent crude oil (BZ=F) rising back over $105.

Futures attached to the Dow Jones Industrial Average (YM=F), the benchmark S&P 500 (ES=F) fell 0.1%, and futures attached to the tech-heavy Nasdaq 100 (NQ=F) all fell into the red.
