KYIV, Ukraine >> A Russian missile tore through an outdoor market in eastern Ukraine on Wednesday, killing 17 people and wounding dozens, as U.S. Secretary of State Antony Blinken returned to the country with more than $1 billion in new American funding for Ukraine, including military and humanitarian aid.

Blinken’s fourth visit to the country was overshadowed by the strike in the city of Kostiantynivka, near the front line in the Donetsk region, that turned the marketplace into an inferno. It was one of the deadliest bombardments of civilians in the 18-month-old war. In addition to the dead, at least 32 people were wounded.

“Those who know this place are well aware that it is a civilian area,” President Volodymyr Zelenskyy said at a news conference with the Danish prime minister in Kyiv. “There aren’t any military units nearby. The strike was deliberate.”

White House press secretary Karine Jean-Pierre said such brutal Russian attacks underscore “the importance of continuing to support the people of Ukraine.”

Blinken’s visit was aimed at assessing Ukraine’s 3-month-old counteroffensive and signaling continued U.S. support as some Western allies express worries about Kyiv’s slow progress against invading Russian forces.

“We want to make sure that Ukraine has what it needs, not only to succeed in the counteroffensive but has what it needs for the long-term, to make sure that it has a strong deterrent,” Blinken said. “We’re also determined to continue to work with our partners as they build and rebuild a strong economy, strong democracy.”

About $175 million of the total is in the form of weaponry to be provided from Pentagon stockpiles and another $100 million is in the form of grants to allow the Ukrainians to purchase additional arms and equipment, according to the State Department.

Noting progress in the counteroffensive, Blinken said the new aid “will help sustain it and build further momentum.” He said the new military assistance would be bolstered by the arrival of U.S. Abrams tanks in the fall and the training of Ukrainian pilots on F-16 fighter jets to complement training in Europe.

In addition to the military assistance, Blinken announced nearly $805 million in non-arms-related aid for Ukraine, including $300 million for law enforcement, $206 million in humanitarian aid, $203 million to combat corruption and $90.5 million for removing mines, the State Department said.

The package also includes a previously announced $5.4 million transfer to Ukraine of frozen Russian oligarch assets.

The aid announced by Blinken comes from money previously approved by Congress. President Joe Biden has requested another $21 billion in military and humanitarian aid for Ukraine for the final months of 2023, but it’s not clear how much — if any — will be approved.

Many Republican lawmakers are wary of providing more aid, and the party’s presidential front-runner, former President Donald Trump, has criticized U.S. financial support. Opinion polls also have shown a decline in support for the war by the American public.

Biden and the Pentagon have said repeatedly they will support Ukraine for as long as it takes. As of Aug. 29, there was approximately $5.75 billion left in the already approved funding for weapons and equipment taken from existing Pentagon stocks.

Blinken was to discuss other issues, including support for Ukraine’s economy, building on his June announcement of $1.3 billion to help Kyiv rebuild, with a focus on modernizing its energy network, which was bombarded by Russia last winter.

Kremlin spokesman Dmitry Peskov said U.S. assistance to Ukraine “can’t influence the course of the special military operation” — Moscow’s euphemism for the war.

Blinken arrived in Kyiv for an overnight visit hours after Russia launched a missile attack on the city.

On the train to Kyiv, Blinken met with the Danish prime minister, Mette Frederiksen, who was also on an official visit, and thanked her for Denmark’s leadership in training Ukrainian pilots on F-16s and for promising to donate the fighter jets to Ukraine, according to State Department spokesperson Matthew Miller.
