More than $1 million was raised in Sam Houston Park in Houston this weekend to help break the cycle of poverty. The Aga Khan Foundation (AKF) Walk happens annually to raise awareness and funds for quality of life programmes around the world. "The universal values of self-reliance, pluralism and respect for human dignity have been at the core of AKF's work for the past 50 years and will remain our touchstone for years to come," said Aly Valiani, Vice Chair for AKF.
