LONDON: At a London sports stadium, Maya Hassan looked on with pride as around 30 women, almost all of them Muslim and from ethnic minorities, took part in a self-defense class she organised in response to a wave of violent and racist attacks on Muslims and migrants. The 28-year-old martial arts expert said she wanted to help black women learn how to deal with abuse and build connections and confidence after more than a week of unrest at mosques, asylum seeker hotels and police.
