Ukrainian President Volodymyr Zelenskyy said on Wednesday that Ukraine needed "new energy" as he ordered the biggest government reshuffle since the start of the conflict with Russia two and a half years ago.

"We need new energy today, and these steps are related only to the strengthening of our state in different directions," Zelenskyy told the media.

The Ukrainian parliament on Wednesday held a session and accepted the resignations of a deputy prime minister, the strategic industries minister and two other ministers, according to local media reports. 

But the session did not consider the resignation of Foreign Minister Dmytro Kuleba, who submitted his letter early on Wednesday. 

A source close to the presidential office told AFP news agency that Zelenskyy and Kuleba "will discuss and decide" his future post.
