SEOUL, April 12 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares fell 1% on Tuesday to their lowest close in nearly a month amid cautious mood ahead of the U.S. inflation data. The Korean won weakened, while the benchmark bond yield rose.

** The benchmark KOSPI ended down 26.34 points, or 0.98%, to 2,666.76, marking the lowest close since March 16.

** Among the heavyweights, technology giant Samsung Electronics fell 1.33% and peer SK Hynix lost 0.45%, while battery maker LG Energy Solution dropped 3.29%.

** Foreigners were net sellers of 465.1 billion won ($377.34 million) worth of shares on the main board, extending selloffs to a fifth straight session.

** Stocks fell as worries of global economic slowdown and U.S. inflation continued, said Mirae Asset Securities' analyst Kim Seok-hwan.

** South Korea's finance minister said he will lobby for the country to be included in the Morgan Stanley Capital International (MSCI) developed market index when he meets the index provider next week.
