Mexico's archdiocese says young people delivering relief supplies to earthquake victims in the southern state of Oaxaca have been attacked and robbed. The archdiocese's information service says unidentified gunmen set upon a pick-up truck driven by the group on Tuesday. Carlos Arvizu, administrator of the Papa Francisco Pro Felicitas foundation, said on Wednesday that one person was shot, another was beaten and a woman was raped. A photograph shows a pickup with numerous bullet impacts. The attackers stole the group's mobile phones and about $2,000. Oaxaca was rocked by a magnitude 8.1 earthquake on September 7 and a 6.1 earthquake on September 23. Since the first earthquake, youths delivering aid from churches have been a common sight in Juchitan and other hard-hit communities.
