Obama says US is still analyzing North Korea's recent actions

US President Barack Obama said on Sunday North Korea is engaging in provocative behavior and the United States is still analyzing the country's recent actions, after North Korea said it conducted a submarine-launched ballistic missile test.
"What is clear is that North Korea continues to engage in continuous provocative behavior, that they have been actively pursuing a nuclear program, an ability to launch nuclear weapons," Obama said at a joint news conference with German chancellor Angela Merkel.
"And although more often than not they fail in many of these tests, they gain knowledge each time they engage in these tests," he added.
