KYIV: Ukrainian President Volodymyr Zelensky said he was counting on a “strong” US response to Russia’s intensifying attacks against Ukraine since a meeting between President Donald Trump and President Vladimir Putin on August 15 in a failed bid to end the raging war.

“It is important that there is a broad response from partners to this attack today,” said Zelensky in his evening address, adding that Putin was “testing the world.”

“We are counting on a strong response from America. That is what is needed.”

Zelensky’s statement followed Trump remarks that he was ready to impose more sanctions on Russia, after the Kremlin unleashed its biggest-ever aerial barrage at Ukraine.

Russian missiles and drones rained down across Ukraine early Sunday, killing four people and setting government offices in the capital Kyiv ablaze.
