In Quetta, the city that has become the epicentre of sectarian violence in Pakistan, minority Shia candidates are braving death threats to make themselves heard. One of those, a doctor and former soldier, is also the first female candidate to run for office in national elections. She risks her life to campaign in the elections, because, she says, she is brave and Pakistan needs to be brave as well. Al Jazeera's Imtiaz Tyab reports from Quetta.
