An Indian-origin MP in Canada has slammed the provocative pro-Khalistani posters labelling some senior Indian diplomats as "killers" and warned that the "snakes in our backyard are raising their heads and hissing." Chandra Arya, a Liberal Party politician, who hails from Karnataka, also underlined that it was only a question of time when they would bite to kill, an apparent reference to the growing menace posed by Khalistan supporters in Canada.
