President Moon Jae-in's approval rating dropped slightly from a week earlier this week, a survey showed Friday, amid renewed concerns over public safety caused by a recent chartered fishing boat accident that left more than a dozen people killed.

In a survey conducted by Gallup Korea, 74 percent of 1,005 adults surveyed said they approved of the way the president managed state affairs, down 1 percentage point from a week earlier.

The weekly poll was conducted from Tuesday through Thursday. It had a margin of error of 3.1 percentage points.

The on-week drop was apparently caused by the tragic accident that took place Sunday, leaving 15 people dead.

Those who said they disapproved of Moon's management of state affairs accounted for 18 percent of all respondents, up 1 percentage point from the previous week.
