Three in four Americans are either concerned (40 percent) or very concerned (35 percent) that Iran will further retaliate against the United States' airstrikes on three nuclear facilities in Iran, according to a poll released Tuesday. One in four was not very concerned (19 percent) or not concerned at all (6 percent).

Seventy-five percent of U.S. adults said they were concerned or very concerned that Iran would lash out against the United States for the June attacks on three of its nuclear sites.
