Soccer-Russia and South Korea goalless at halftime

CUIABA, Brazil, June 17 (Reuters) - Russia and South Korea were goalless at halftime in their Group H match on Tuesday with the game suddenly sparking into life after a dull first half-hour. Russia posed no attacking threat until a powerful 40-yard free-kick from Sergey Ignashevich after 31 minutes had to be beaten away by South Korean goalkeeper Jung Sung-ryong. South Korea went close just three minutes later when Koo Ja-cheol saw his shot deflected narrowly wide with Russia's goalkeeper Igor Akinfeev stranded. (Editing by Patrick Johnston)
