Members of a Catholic youth group were reportedly beaten, raped and shot while they were bringing aid to earthquake victims in south Mexico.

The volunteers, who were delivering food and relief aid to communities affected by the earthquakes in Oaxaca on Tuesday morning, were intercepted by unidentified gunmen who shot up their cars. The assailants reportedly raped one of the girls, beat one of the men and shot another in the neck.

The suspects took away the supplies, the youths’ cellphones and approximately $2,300 collected to purchase items to donate to the Isthmus of Tehuantepec region, according to a statement from the Archdiocese of Mexico City.
