TOKYO (AP) — The three new missiles North Korean leader Kim Jong Un has tested over the past week are eerily familiar to military experts: They look just like a widely copied missile the Russian military has been actively trying to sell abroad for years.

Ending a pause in ballistic missile launches that began in late 2017, Kim supervised the launch of the first missile from the country's east coast on Saturday and two more from the west on Thursday.

It's still unclear if the North bought the missiles or built them itself, but experts say they look just like a nuclear-capable ballistic missile that has long been a source of tension in Europe and was behind the Trump administration's decision to suspend a longstanding arms treaty with Moscow in February.
