have unleashed a wave of violence across 20 Mexican states. They torched businesses and erected burning blockades in retaliation to the killing of their leader, Nemesio Oseguera Cervantes, better known as "El Mencho", who died in custody on Sunday shortly after being captured by Mexican special forces. El Mencho, Mexico's most wanted man, was seriously injured in a firefight between his bodyguards and the military commandos deployed to capture him. He died while the military was transporting him from the town of Tapalpa, in Jalisco state, to the capital, Mexico City. At least six of El Mencho's security guards were also killed in the operation, while three members of the Mexican military were injured, the defence ministry said. As news of El Mencho's death spread, members of his cartel launched attacks in many towns and cities where the CJGN is active. In some towns, they blocked roads by throwing spikes and nails on to the tarmac - in others, they commandeered buses and other vehicles they then torched in the middle of the road. Cartel members also set alight dozens of banks and local businesses such as pharmacies. (BBC)
