SEOUL, Oct 16 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares fell on Monday amid weakened risk sentiment due to the uncertainty of military conflict in the Middle East.

** The benchmark KOSPI closed down 19.91 points, or 0.81%, at 2,436.24, after falling as much as 1.37% during the session.

** Egypt, Israel and the United States agreed to a ceasefire in southern Gaza to begin at 0600 GMT on Monday, coinciding with the re-opening of the Rafah border crossing.

** The KOSPI recouped some of its early losses following the news.

** "The market was in usual 'war trading', with stock prices and bond yields falling, the dollar strengthening, and gold gaining on increased geopolitical risk," said Na Jeong-hwan, an analyst at NH Investment Securities.

** South Korea's finance minister said authorities would closely monitor financial markets and vowed to take response measures if needed.

** Among index heavyweights, chipmaker Samsung Electronics fell 1.03% and peer SK Hynix lost 0.48%, while battery maker LG Energy Solution slid 2.07%.

** Hyundai Motor shed 0.16% and sister automaker Kia Corp lost 0.36%, while search engine Naver and instant messenger Kakao ended down 1.09% and 0.12%, respectively.

** Of the total 933 traded issues, 252 shares advanced, while 645 declined.

** Foreigners were net sellers of shares worth 207 billion won ($152.90 million) for the day on the main board. It was a 14th consecutive session where selling was more than buying.

** The won ended onshore trade at 1,353.7 per dollar, 0.27% lower than its previous close at 1,350.0.

** The most liquid three-year Korean treasury bond yield rose by 0.9 basis point to 3.968%, while the benchmark 10-year yield rose by 0.3 basis point to 4.178%. ($1 = 1,353.8700 won) (Reporting by Jihoon Lee; Editing by Sonia Cheema)
