KYIV, Ukraine, July 17, 2025 (BSS/AFP) - A Russian strike on a central square in Ukraine's frontline town of Dobropillia killed at least two people and wounded 22, authorities said Wednesday in a new blow to US President Donald Trump's calls for Moscow to end its invasion.

Russia fired hundreds of drones, artillery and a ballistic missile at Ukraine early Wednesday, defying Trump's made Monday to reach a peace deal within 50 days or face severe sanctions.

According to regional authorities, Russia dropped a 500-kilogramme (1,100 pound) bomb on Dobropillia, which is just 20 kilometres (12 miles) from the frontline.

Ukraine's President Volodymyr Zelensky said rescue operations were underway in Dobropillia after the bomb strike that had targeted "an ordinary shop and shopping pavilions."

He called the attack "horrific, senseless terror" and said "there is no military sense in their strikes."

Vadym Filashkin, head of Ukraine's embattled Donetsk region, said two people were killed and 22 wounded.

Filashkin published footage of the square, with several fires and low-rise buildings severely damaged and covered in rubble.

He said the rush hour attack hit 54 shops and 13 buildings around the crowded square.

Officials said rescue workers clearing the rubble could find more victims.

Dobropillia is a quiet town not far from the eastern Ukraine frontline that has faced regular attacks throughout Russia's invasion.

Russia has stepped up its summer campaign in recent weeks as Washington-mediated ceasefire talks stall.

Trump has said he is "disappointed" in Russian President Vladimir Putin, who has kept attacking Ukraine as if the two leaders' phone conversations "didn't mean anything."

Some two dozen people were wounded across Ukraine in other night-time Russian attacks, officials said.

In Russia, officials said one person was killed in a Ukrainian drone attack on the city of Voronezh, some 200 kilometres from Ukraine's border.

- Reshuffle in Kyiv -

The attacks came as Zelensky unveiled a government reshuffle -- replacing his prime minister and defence minister as he aims to breathe new life into his team, with no end of the war in sight.

Ukraine's new prime minister will be Yulia Svyrydenko -- an economy minister known for finalising a crucial natural resources deal with the United States.

Zelensky has indicated that Defence Minister Rustem Umerov, who had taken part in negotiations with Russia, will be the next Ukrainian ambassador to Washington.

The outgoing prime minister, Denys Shmygal, will take over the defence ministry brief, Zelensky has said.

In Brussels, the European Commission on Wednesday proposed establishing a fund of up to 100 billion euros ($115 billion) to support Kyiv, calling it a "long-term commitment to Ukraine's recovery and reconstruction."

The EU's anti-crime bodies Europol and Eurojust said they had coordinated an international operation to dismantle a pro-Russian hacking group accused of launching thousands of online attacks against Ukraine and its allies.

The operation, they said, involved 12 countries and led to the arrest of two people -- in France and Spain.
