Americans were anxious over a conflict between the US and Iran and worried the violence could escalate after President Donald Trump ordered the bombing of Iranian nuclear facilities, according to a Reuters/Ipsos poll that closed on Monday.

The three-day poll began after the US airstrikes and ended early Monday before Iran launched missiles at a US air base in Qatar. Hours after the Iranian attack, Trump declared that Israel and Iran agreed to a “complete and total ceasefire” which would fully take effect in 24 hours, bringing about an “official end to the 12-day war.”

According to the survey, some 79% of Americans surveyed said they worried “that Iran may target US civilians in response to the US airstrikes,” with 84% stating they worried in general about the growing conflict.

The poll also showed Americans were similarly concerned about their country’s military personnel stationed in the Middle East.

The poll, which surveyed 1,139 US adults nationwide, underscored deep divisions in America over what Washington should do next and highlighted the political risks faced by Trump, whose presidential approval rating fell to 41%, the lowest level of his current term in office that began in January.

Some 36% of respondents – including 13% of Democrats and 69% of Republicans — said they supported the strikes, which took place early Sunday. 45% — including 74% of Democrats and 17% of Republicans — said they opposed the strikes. The poll had a margin of error of 3 percentage points, and the public’s view of the conflict could evolve in the days and weeks ahead.

Only 32% of people in the survey said they supported continued US airstrikes, compared to 49% who said they were opposed. Within the Republican Party, 62% backed further strikes and 22% were opposed. Republicans were more deeply divided when asked if they supported an immediate end to US involvement in the conflict with Iran, with 42% saying Washington should end its involvement now and 40% opposed to the idea.

Significant majorities of Democrats were opposed to further strikes on Iran and in favor of ending the conflict immediately.
