Former Philippine President Rodrigo Duterte said he takes full responsibility for his administration's "war on drugs", in a video message posted on his Facebook account, as he braces for a legal battle at the International Criminal Court.

President Donald Trump escalated his trade war Tuesday, announcing on Truth Social that he will double the tariffs on steel and aluminum coming from Canada from 25% to 50% in retaliation for new trade restrictions put in place by the province of Ontario this week.

It started with tariffs, but the trade war is quickly escalating beyond import taxes into a broader tit-for-tat battle.
