U.S. Secretary of State Antony Blinken joined a meeting of EU foreign ministers in Brussels by video link on Monday. Topping the agenda at the meeting were tensions over Ukraine with Russia, which has massed tens of thousands of troops at the border, though it denies planning an invasion. The EU has been largely sidelined by direct Russia-U.S. talks, the latest round of which took place in Geneva on Friday between Blinken and Russian Foreign Minister Sergei Lavrov. Arriving at the meeting on Monday, EU ministers called for unity and threatened severe consequences if Russia were ever to invade.
