SEOUL, Feb 25 (Reuters) - Round-up of South Korean financial markets:
** South Korean shares closed 1% higher on Friday, bouncing back from a one-month low hit in the previous session, although the benchmark index marked its worst week in four on Russia-Ukraine jitters. The won and the benchmark bond yield rose.
** The KOSPI closed up 27.96 points, or 1.06%, at 2,676.76, after declining 2.60% to the lowest level since Jan. 28 on Thursday.
** The index declined 2.47% on a weekly basis, extending its losing streak to a third week. It has lost 10.10% so far this year.
** Among heavyweights, chip giants Samsung Electronics and SK Hynix rose 0.56% and 0.41%, respectively, while platform company Naver added 3.97%.
** Ukrainian forces battled Russian invaders on three sides on Thursday after Moscow unleashed the biggest attack on a European state since World War Two, prompting tens of thousands of people to flee their homes.
** U.S. President Joe Biden hit back at Russia with a wave of new sanctions that impede Russia's ability to do business in major currencies along with sanctions against banks and state-owned enterprises.
