Dalilah Muhammad bagged her second gold medal of the World Championships on Sunday as the United States cruised to victory in the women's 4x400m relay. Muhammad, who set a world record en route to her 400m hurdles gold on Friday, ran a blistering third leg for the USA who won in a time of 3min 18.92sec. Poland took silver in 3:21.89 while Jamaica pipped Great Britain for bronze in 3:22.37.

The USA victory also sees Allyson Felix extend her record tally of world championship gold medals. The 33-year-old American, who did not run in the final but featured in the early rounds, now has 13 gold medals.
