The head of Canada’s opposition has called for Justin Trudeau to be fired for saying his government would abide by an international arrest warrant for Benjamin Netanyahu, the Israeli prime minister.

Asked by a reporter on Thursday if he would allow an arrest to happen in Canada or if he would step in to prevent it, Trudeau said “it’s really important that everyone abide by international law. This is something we’ve been calling on from the beginning of the conflict.”

The United States, like Israel, is not a party to the ICC, and has condemned the warrants against Netanyahu and former Israeli Defense Minister Yoav Gallant.
