OCOSINGO, Mexico (AP) — Members and supporters of the Zapatista indigenous rebel movement celebrated the 30th anniversary of their brief armed uprising in southern Mexico on Monday even as their social base erodes and violence spurred by drug cartels encroaches on their territory.

Hundreds gathered in the remote community of Dolores Hidalgo in the preceding days to mark the occasion. Some 1,500 young Zapatistas donning uniforms — black balaclavas, green caps and red kerchiefs — stood in formation listening to speeches early Monday.
