Security concerns rise after attack on Japanese PM and raid on suspect's home.

Police have raided the home of a man suspected of throwing an explosive near Japanese Prime Minister Fumio Kishida, as the leader vowed to ensure maximum security to keep global dignitaries safe during G7 meetings in the country next month. The attack came nine months since former Prime Minister Shinzo Abe died after being shot at a political rally by a man using a homemade gun in an assassination that rocked Japan and sparked criticism over whether enough security was in place.
