Japan's Defense Minister Tomomi Inada called North Korea's regular nuclear missile tests a provocation.

The US Independence Day could become a reason for another missile launch. It is also not excluded that Pyongyang is sending an alert to the participants of the upcoming G20 summit, which will be held in Hamburg on July 7-8, TASS reported quoting Tomomi Inada.

North Korea fired an intermediate range missile on Tuesday, which appeared to have landed in the Japanese exclusive economic zone (EEZ).
