Japanese Defense Minister Taro Kono says Japan has been working with other countries in analyzing information about the attack on Saudi Arabia's oil facilities.
Kono told reporters on Wednesday that Iran-backed Houthi insurgents in Yemen have claimed responsibility for the attack, but the claim has been inconclusive. He said Iran's involvement has not been confirmed as well.
Kono said Japan has a huge role to play because it can talk with the US about anything and is also trusted by Iran and countries of the Middle East.
He said he is not sure how the Defense Ministry should get involved, but he will focus on supporting the Foreign Ministry.
