Russia’s invasion of Ukraine entered its sixth day on Tuesday, with a huge convoy of Russian tanks and armored vehicles inching closer to the capital of Kyiv and fighting intensifying there and in other big cities.
Russia stepped up shelling of Ukraine’s second-largest city, Kharkiv, and pounded several civilian buildings. More than 70 Ukrainian soldiers were reportedly killed when Russian artillery hit a military base in Okhtyrka, a city of about 50,000 people between Kharkiv and Kyiv.
The Russian economy is paying a price for the invasion, with Western sanctions causing the ruble to tumble and restricting the country’s use of its huge foreign currency reserves.
Here’s a look at things to know about the Russia-Ukraine conflict.
