LONDON (AP) — Rim Jong Sim won North Korea's third weightlifting gold medal in the London Olympics when she clinched the women's 69-kilogram class Wednesday in a dramatic finish.

Rim lifted a total weight of 261 kilograms but was challenged until the end by Romania's Roxana Cocos, who would have moved into first placed if she hadn't failed with her final lift.

Cocos finished with silver and Maryna Shkermankova of Belarus got the bronze.

The top-ranked lifter in the weight class, Russia's Oxana Slivenko, withdrew from the Olympics due to injury.

Rim, 19, was the bronze medalist at last year's junior world championships with a 225-kilogram total. She improved on that result with an additional 36 kilograms, continuing a streak of spectacular performances by North Korean lifters in London.

North Koreans Om Yun Chol and Kim Un Guk won gold medals in the men's two lowest weight categories, while Ryang Chun Hwa won bronze for North Korea in the women's 48-kilogram class.

Only China has done better in the weightlifting competition in London.
