Japan's Prime Minister Fumio Kishida, a day after escaping an apparent attack, vowed to ensure the safety of Group of Seven dignitaries visiting his country, beginning with tighter security for climate ministers gathering in Sapporo.
"My security has become even heavier this morning. It's so tight I think it is going to be difficult to go out into the city," Japan's environment minister, Akihiro Nishimura, said at a the hotel in the northern Japanese city where he was hosting his G7 counterparts.
