In Britain and other parts of Europe, at-home COVID-19 tests have long been available for free and have become a part of everyday life. Now, US President Joe Biden is trying to beef up access for at least 150 million Americans with private health insurance. And, Russia has been moving thousands of troops to its border with Ukraine in recent months. Tensions between the two countries are now at a high point. Also, fighting around Yemen’s oil-rich city of Marib has intensified. The last northern Yemeni city loyal to the Saudi-backed Yemeni government is surrounded on three sides by Houthi forces, which may be a critical turn in the yearslong civil war.
