South Korean shares fell more than 1% on Thursday as escalating tensions in the Middle East dampened investor risk appetite and triggered selling across major sectors, Reuters reported.
The benchmark KOSPI fell 96.61 points, or 1.37%, to 6,955.03 as of 0058 GMT, according to Reuters.
The decline came after Iran said on Wednesday that it had attacked 10 ships near the Strait of Hormuz after the United States sank five Iranian oil tankers. The developments marked the biggest wave of attacks on shipping by both sides since the six-month-old war began, Reuters reported.
