Sweden's Sarah Sjostrom broke the women's 100m butterfly world record for the second time in 24 hours to win gold in the final at the world swimming championships on Monday.

Sjostrom clocked 55.64 seconds to shave 0.15s off the record she set in Sunday's semi as she retained the world title she won two years ago in Barcelona.

Denmark's Jeanette Ottesen, the 50m butterfly world champion, took silver in 57.05 with China's Lu Ying claiming bronze with 57.48.

This was the third world record to fall in Kazan after Katie Ledecky bettered her own 1500m freestyle time in Monday morning's heats when the United States' Olympic champion swam 15 mins 27.71 secs.
