German Chancellor Angela Merkel and French President Emmanuel Macron on Sunday urged tougher EU sanctions against North Korea after Pyongyang said it had tested a hydrogen bomb.

"The chancellor and the president are in agreement that North Korea has trampled on international law and that the international community must therefore react with determination against this new escalation," Merkel's office said in a statement after she spoke on the phone with Macron, adding that both leaders "are calling for tougher EU sanctions against North Korea".
