Only one in four Americans approves of the US strikes that killed Iran’s leader on Saturday, while about half, including one in four Republicans, believe President Donald Trump is too willing to use military force, according to a Reuters/Ipsos poll.

Reuters reports that 27 per cent of respondents said they approved of the strikes, while 43pc disapproved and 29pc were not sure.

About nine in 10 respondents said they had heard at least a little about the strikes, which began early on Saturday.

Some 56pc of Americans think Trump, who has also ordered strikes in Venezuela, Syria and Nigeria in recent months, is too willing to use military force to advance US interests.

The vast majority of Democrats — 87pc — held this view, as did 23pc of Republicans and 60pc of people who don’t identify with either political party.

The poll, which began on Saturday after the strikes got underway, has gathered responses online from 1,282 US adults nationwide. It has a margin of error of three percentage points.
