GUWAHATI, May 7: On April 23, 1980, firebrand student activist Dulal Sarma slashed open his chest with a blade and wrote in bold letters with his own blood on a street in front of Guwahati Refinery at Noonmati: “Tez dim, tel nidiu” (We will give blood, not oil). It was a defining moment of the historic anti-foreigners movement in the State, which inspired thousands of others to come out on the streets to support the agitation, led by the All Assam Students’ Union (AASU).
