Birmingham Indoor Grand Prix: Genzebe Dibaba shatters two-mile record

Ethiopia's Genzebe Dibaba breaks the two mile world record in an eventful day at the Birmingham Indoor Grand Prix.

James Dasaolu won the men's 60m but could miss the World Indoor Championships at the start of next month after injuring his hamstring.

There were also wins for Scotland's Laura Muir in 1500m and Murielle Ahoure, who beat Shelly-Ann Fraser-Pryce in the women's 60m in a photo-finish.
