U.S. President Donald Trump arrived in the Polish capital of Warsaw on Thursday, his first stop in Europe during his current trip. During his meeting with Polish President Andrzej Duda, he sent a threat to North Korea in light of the country’s recent intercontinental ballistic missile test.

Trump said that the U.S. is planning to respond to North Korea’s recent test but did not provide any details about the plans. The U.S. president told reporters that “something will have to be done about” North Korea’s actions.

Trump called on the countries of the world to work together in order to contain Pyongyang, calling the regime’s actions “very bad behavior.” In addition, Trump used the meeting to pass along a message to the NATO member states, calling on them to uphold their financial obligations.

Trump will also meet with other leaders from Western Europe in order to discuss topics such as trade, energy and immigration. Later today, he will address the Polish nation in a speech. According to reports, Trump will praise the Polish people for overcoming dark regimes throughout the last century.

This afternoon, Trump will leave Poland and head to the G20 summit in Hamburg, Germany. While Trump will sit down with several leaders during the summit, the world will be watching as he meets with Russian President Vladimir Putin for the first time.
