Russia confirms big retreat near Kharkiv as Ukraine offensive advances

War in Ukraine: What you need to know

The latest: Grain shipments from Ukraine are gathering pace under the agreement hammered out by Ukraine, Russia, Turkey and the United Nations in July. Russia’s blockade of Ukrainian Black Sea ports had sent food prices soaring and raised fears of more hunger in the Middle East and Africa. At least 18 ships, including loads of wheat, corn and sunflower oil, have departed.

The fight: The conflict on the ground grinds on as Russia uses its advantage in heavy artillery to pummel Ukrainian forces, which have sometimes been able to put up stiff resistance. In the south, Ukrainian hopes rest on liberating the Russia-occupied Kherson region, and ultimately Crimea, seized by Russia in 2014. Fears of a disaster at the Zaporizhzhia Nuclear Power Station remain as both sides accuse each other of shelling it.

The weapons: Western supplies of weapons are helping Ukraine slow Russian advances. U.S.-supplied High Mobility Artillery Rocket Systems (HIMARS) allow Ukrainian forces to strike farther behind Russian lines against Russian artillery. Russia has used an array of weapons against Ukraine, some of which have drawn the attention and concern of analysts.
