US President Joe Biden announces a new weapons package for Kyiv, as he meets his Ukrainian counterpart Volodymyr Zelensky during a bilateral meeting on the sidelines of the G7 summit in Hiroshima.

Biden says the package will include "ammunition, artillery, armored vehicles" -- days after giving allies the okay to transfer advanced F-16 jets to Ukraine.

-Ukraine's Zelensky wins new diplomatic, military support from G7-

Zelensky secured more arms, munitions and "unwavering" diplomatic support from G7 allies in Hiroshima Sunday.

Meeting leaders from a bloc of rich democracies, Zelensky won a commitment from Biden to provide yet more "ammunition, artillery, armored vehicles" on top of access to F-16 jets.

Top Zelensky aide Andriy Yermak said the US package included additional ammunition for HIMAR rocket launchers, artillery shells, anti-tank guided missiles and thermal imaging systems worth USD 375 million.

Zelensky's surprise trip to Japan has been a major diplomatic coup, putting his country at the top of the agenda.

But success in the negotiating rooms contrasted sharply with difficulties on the ground, as he reflected on the months-long battle for Bakhmut and the new Russian announcement to have taken control of the eastern city.

Asked about the fate of the former salt-mining town of 70,000 people, Zelensky was notably downbeat, saying "you have to understand there is nothing" there.

"For today, Bakhmut is only in our hearts," he said.

Saturday, Russian President Vladimir Putin congratulated mercenaries from the Wagner organization and regular units for the operation to "liberate" the town.

Zelensky's invitation to visit Hiroshima, a city synonymous with the horrors of nuclear war, was a "deeply meaningful" symbol of support, according to host Fumio Kishida, Japan's prime minister.

"By inviting President Zelensky to Japan, we demonstrated the unwavering solidarity of G7 with Ukraine," he said.
