KYIV, Ukraine (AP) – Ukrainian President Volodymyr Zelenskyy thanked the United States for the new package of $800 million in military aid, which he said was “just what we were waiting for.”

The latest military aid, announced Thursday by President Joe Biden, includes heavy artillery, ammunition and drones for the escalating battle in the Donbas region of eastern Ukraine.

Zekenskyy has urged Western countries to speed up the deliveries of weapons to help Ukraine fend off the Russian offensive.

“The occupiers continue to do everything possible to give themselves a reason to speak about at least some kind of victory,” Zelenskyy said late Thursday in his nightly video address to the nation. “They are building up their forces, bringing in new tactical battalions and trying even to begin a so-called ‘mobilization’ in the regions they occupy in Ukraine.”

Zelenskyy also warned Ukrainians living in areas of southern Ukraine under the control of Russia troops not to provide them with their IDs, which he said could be used “to falsify a so-called referendum on our land” to create a Moscow-friendly government.
