NEW YORK (AP) — Some calm is returning to Wall Street, and U.S. stocks are rising on Monday, while oil prices are giving back some of their initial spurts following Israel’s attack on Iranian nuclear and military targets at the end of last week.

As Israel and Iran exchanged more attacks, stock markets mostly rose even as worries remained about possible oil supply interruptions.

Stock futures rebounded slightly early Monday as the spike in oil prices due to the escalating conflict between Israel and Iran eased for a moment. Stock gains were muted as investors remained concerned about the rising geopolitical risk to the global economy.

From the BBC World Service: There have been days of missile strikes between Israel and Iran, and oil markets are responding.

Ukrainian President Volodymyr Zelenskyy says rising global oil prices following Israeli strikes on Iran will strengthen Russia by increasing its oil revenues, aiding its war effort in Ukraine.

Oil futures soared in electronic trade late Thursday after Israel's attack on Iran, with West Texas Intermediate crude, the U.S. benchmark, up nearly 10% in electronic trade on the New York Mercantile Exchange.

Israel launched an expanded assault on Iran on Sunday, targeting its energy industry and Defense Ministry headquarters, while Tehran unleashed a deadly barrage of missiles.
