Gunmen who attacked a group of youths playing soccer killed seven people in the violent northern border city of Ciudad Juárez. The latest drug prohibition violence came on the eve of a one-day visit to Mexico by US secretary of State Hillary Clinton to discuss bilateral cooperation against the country's powerful drug trafficking organizations. The stadium where the shooting occurred was inaugurated just four months ago as part of a campaign called "We are all Juarez" that the local government has hoped will help stem a wave of drug prohibition related violence.
