Reuters - German Foreign Minister Heiko Maas said on Monday he will travel to Washington to meet with U.S. Secretary of State Mike Pompeo on Washington�s stance on an international nuclear deal with Iran.

The United States earlier in the day demanded Iran make sweeping changes - from dropping its nuclear program to pulling out of the Syrian civil war - or face sanctions as the Trump administration hardened its approach to Tehran.

�From here I will actually travel to Washington to have a meeting with Secretary Pompeo, and take advantage of that meeting to talk about this,� Maas said in response to a question from a journalist about the Iran deal.

Maas spoke to reporters in Buenos Aires at the end of a G20 meeting in the Argentine capital.
