Here's a look at the latest state of control in Ukraine 

The battlefield is "complicated but controlled" as Ukrainian forces push ahead with their counteroffensive to take back parts of the country seized by Russia in the early days of Moscow's invasion, Commander-in-Chief of Ukraine's Armed Forces Valerii Zaluzhnyi said Thursday.

Take a look at where the state of control stands in Ukraine:






Russian President Vladimir Putin said on Friday that Moscow would shut down corridors established for the export of Ukrainian grain if they are used to carry out “terrorist attacks.”

"If it turns out that humanitarian corridors are used for terrorist attacks, this will put the grain agreement into question," Putin told reporters in the Kazakh capital of Astana. 

Putin on Friday suggested a link between the safe corridors and the recent attack on the Kerch bridge in Crimea, claiming that it’s possible the explosives for the attack were sent by sea from Odesa.

Some background on the grain deal: Since July, ships carrying grain from Ukrainian ports in Odesa have been allowed to navigate a safe corridor through the Black Sea as part of a UN-brokered agreement between Kyiv and Moscow after five months of Russian blockade.

The deal is set to expire in November.

Putin's remarks come as a Russian diplomat Gennady Gatilov suggested on Thursday that his country could potentially leave the deal. “If we see nothing is happening on the Russian side of the deal – export of Russian grains and fertilizers – then excuse us, we will have to look at it in a different way,” he said, according to Reuters. "We are not against deliveries of grains but this deal should be equal, it should be fair and fairly implemented by all sides." 

Ukraine says it's developing new technology to counter Iranian-made drones

Ukraine says it's developing new technology to combat the waves of attacks by Iranian-made drones that Russia has bought.

Oleksii Reznikov, the Ukrainian defense minister, said Friday that he believed Russia currently had some 300 Iranian-made attack drones, "and they are trying to purchase a few thousand more such drones. We will see whether it happens or not, but we have to be prepared."

"We are developing systems for their suppression ... We disassemble the drones to [see] the details, see what kind of electronic 'brains' they have inside and accordingly prepare various countermeasures," he added.

The Russians were using Iranian "kamikaze" drones in groups, partly to detect the disposition of Ukrainian air defenses, Natalia Humeniuk, spokesperson for the Ukrainian military in the south, said on Thursday. "Now they are starting to use them almost all over the territory of Ukraine, they are using them from the northern directions, not only from the south."

In the southern region, Ukrainian air defenses shot down 109 drones and 33 had hit targets, Humeniuk added, saying most had been aimed at civilian infrastructure.

"The fact that they are trying to use these drones on critical infrastructure facilities, to deprive us of water, heat, electricity, corresponds to the tactical and technical characteristics and purpose of these kamikaze drones, because they work like matches. [The drone] sets fire to the object and disables it not with an explosion, but more with a fire," she explained

Putin says he has no regrets about Russia's actions in Ukraine

Russian leader Vladimir Putin said on Friday that there is no need for more “massive” strikes against Ukraine “at least for now.”  

His comments come after a week of deadly strikes on civilian targets in Ukraine, including in the Kyiv region.

When asked if he had regrets about his actions in Ukraine, Putin said: "I have no regrets. I want to make it clear that what is happening now is unpleasant.” 

He went on to stress that Russia actions in Ukraine are right and timely.
