June 20 (UPI) -- Stock futures ticked lower before markets reopened Friday morning amid uncertainty among investors over the Middle East and whether the United States was about to get directly involved in the Israel-Iran conflict.

Contracts connected to the Dow Jones Industrial Average dropped more than 83 points, 0.2%; futures for the tech-heavy NASDAQ 100 and broad-market S&P 500 futures were also off by 0.2% at the open after markets were shuttered all day Thursday for the Juneteenth holiday.

However, all three sets of futures recovered lost ground by 8 a.m. EDT, and were roughly flat.

The November contract for Brent Crude Oil, the international benchmark, fell by more than 2% on jitters from comments by Israeli Prime Minister Benjamin Netanyahu that he was weighing expanding airstrikes to "stategic targets" in Iran.
