Concern for the fate of missing Australian brothers in Mexico

Three people have reportedly been arrested in Mexico in relation to two missing Australian brothers, and their friend from the United States. Foreign Affairs Minister Penny Wong says Australian officials have joined in the search for the trio. UPDATE: The family has issued a statement thanking wellwishers and supporters, authorities and the media for their efforts to help in the search. The parents say they are travelling to Mexico to be "as close as possible to the area they were last seen."
