MANILA - Demonstrators on Monday slammed rampant killings and the spike of prices of basic goods under President Rodrigo Duterte's administration, ahead of his third State of the Nation Address.

Scores of militants have converged at the University of the Philippines-Diliman and Philcoa in Quezon City, some waving banners with the slogan, "Oust Duterte."
