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

Stock futures fell sharply and oil prices soared Friday morning as Israel launched strikes against Iran's nuclear program and key personnel, heightening concerns about the possibility of a broader conflict in the region.

Calm returned to Wall Street, and U.S. stocks rallied, while oil prices gave back some of their initial spurts following Israel's attack on Iranian nuclear and military targets at the end of last week.
