The situation in the contested eastern city of Bakhmut remains "under control," with the commander of the country's ground forces taking control of the city's defense, the Ukrainian military said.

The military also said in an update Tuesday that the heaviest combat is concentrated in several zones in the eastern Donetsk and Luhansk regions, and its units have repelled the latest efforts by Russian forces to advance. Over the last day, the General Staff said it repelled 24 Russian attacks.

Here are other headlines:

International assistance: Britain and Poland on Tuesday announced plans to build two temporary villages in Ukraine with housing for people who have been forced to flee their homes due to Russia’s invasion. And on Tuesday, Ukrainian Prime Minister Denys Shmyhal said the government will receive an additional $2.5 billion from the US as a grant to help with state services such as salaries and benefits. The budgetary support is part of a US pledge of $9.9 billion to assist the Ukrainian economy in 2023 and is separate from military assistance. 

Olympic developments: The International Olympic Committee’s (IOC) executive board on Tuesday issued a recommendation to international federations and international sports event organizers that athletes “who actively support the war cannot compete.” But earlier on Tuesday, IOC President Thomas Bach defended plans to allow Russian and Belarusian athletes to participate in international competitions. 

Military defense increases: The Russian Defense Ministry said Tuesday the production of individual types of ammunition will increase seven to eight times by the end of the year. But Western analysts have expressed skepticism that Russia’s military-industrial capacity and supply chains can be accelerated so quickly. In Ukraine, the government announced Tuesday that three new companies financed by donations are ready to deploy Ukrainian-made drones for combat.

Data decisions: The US decided Tuesday to not share data under a key nuclear arms control treaty in response to Russia's announcement that it will not do so either. Meanwhile, the US decision to fly its surveillance drones further south over the Black Sea after a Russian jet collided with a US drone earlier this month “definitely limits our ability to gather intelligence” related to the Ukraine war, a senior US military official tells CNN.
