President Park Geun-hye's job approval rating edged up slightly amid heightened tensions on the Korean Peninsula following North Korea's hydrogen bomb test.

A poll released by polling agency Realmeter Monday showed 44.6 percent of people approved of the job Park is doing, up 2.1 percentage points from a week earlier.

Those who disapproved of Park's job performance came to 51 percent, down 2 percentage points from a week earlier.

It said the uptick in Park's approval rating came as conservatives -- key supporters of Park -- rallied around her after North Korea carried out a fourth nuclear test last week.

South Korea resumed anti-Pyongyang broadcasts along the heavily fortified border with North Korea in retaliation for the nuclear test. On Sunday, one of Washington's B-52 strategic bombers flew in the skies of South Korea in a show of force against North Korea.

The survey was conducted on 2,518 adults on Jan. 4-8 and had a margin of error of plus or minus 2 percentage points. (Yonhap)
