Guwahati, Jan. 23 -- Classes across universities and colleges in Assam were affected on Wednesday due to the "total shutdown" call given by students unions of nine varsities from North East on a day the Supreme Court heard the pleas on Citizenship (Amendment) Act. However, examinations were conducted peacefully as the agitators had kept it out of the shutdown. The students unions of several colleges had called for the boycott. "We will not accept the CAA at any cost. We had called for class boycott today and our agitation will continue till the Act is repealed," Dibrugarh University Post Graduate Students Union General Secretary Rahul Chetry told PTI. Hundreds of students wearing black badges and carrying black flags gathered at the gate of Dibrugarh University and burnt copies of CAA. Chetry informed that 21 universities of North East will organise a "Tiranga March" on January 26....
