The Philippines president called an emergency meeting of top officials on Thursday amid widening political tensions, a day after gunfire rang out at the Senate where a lawmaker wanted by the International Criminal Court has been holed up fearing his arrest.

The senator is wanted by the International Criminal Court for a charge of crime against humanity.

Ronald “Bato” dela Rosa — a senator, former national police chief and ally of imprisoned former president Rodrigo Duterte — faces crimes against humanity charges in The Hague.
