Kneeling inside the Cu Chi tunnels north of Ho Chi Minh City. Cu Chi was the site of heavy US bombing during the #Vietnam #War. The Viet Cong built over 250 kilometers of tunnels to avoid detection and to ambush #American forces between #saigon and #Cambodia. Some of the #tunnels have been widened for #western #tourists, but they still make you feel #claustrophobic. (Pic by @steph_bied)
