High jumper Woo Sang-hyeok has become the first South Korean to win a world indoor championship title.

Woo finished first in the men's high jump at the World Athletics Indoor Championships at the Stark Arena in Belgrade, Serbia on Sunday after clearing two-point-34 meters.

He was the only one among 12 athletes to clear that height.

After securing the gold medal, Woo attempted to clear two-point-37 meters, but failed. He opted not to make a third attempt after touching the bar in the first and second attempts.

With the gold, Woo became the first South Korean to win a championship in a track and field event. He had finished fourth in the men's high jump at last year's Tokyo Olympics, setting a new Korean record of two-point-35 meters.
