MEXICO CITY (Reuters) - Mexico's air force flew tons of grain to the southern state of Oaxaca on Friday as protests by teachers opposed to education reform spread across the country and road blocks led to dwindling food supplies in some remote regions.

Tension in the state intensified after eight people died last month in clashes between police and the protesting teachers, and unrest has flared throughout Mexico.
