(CNN) A curfew has been imposed in Bogota following a second day of anti-government protests in the Colombian capital.

At least three people died in the demonstrations in the Valle del Cauca, in the western part of the country, according to a statement issued on Friday by Colombia's Minister of Defense Carlos Holmes Trujillo.

The nationwide protests and a national strike organized by union workers and social movements began on Thursday. The government closed the state's borders in anticipation of the strike, and deployed tear gas against the protesters in Bogota.

President Ivan Duque, a social conservative who came to power in August 2018, faces widespread discontent over rising unemployment, economic reforms and a deteriorating security situation.
