U.S. stock futures edged higher Wednesday as traders evaluated the ongoing Israel-Iran conflict ahead of a fresh Federal Reserve interest rate decision later in the session.

At 05:20 ET (09:20 GMT), Dow Jones Futures gained 100 points, or 0.2%, S&P 500 Futures inched 20 points higher, or 0.3%, and Nasdaq 100 Futures rose 102 points, or 0.5%.

The main averages on Wall Street ended lower Tuesday, erasing earlier gains, following a fifth day of fighting between Israel and Iran as well as the release of weak retail sales data.

The benchmark S&P 500 slipped by 0.8% and the tech-heavy NASDAQ Composite dropped 0.9%, while the 30-stock Dow Jones Industrial Average declined by 0.7%.
