Ukrainian President Volodymyr Zelenskyy warned that Kyiv has gained intelligence suggesting that Russia is planning a prolonged attack by using Iranian-supplied Shahed drones. 

In an overnight address Monday, Zelenskyy warned that in the two days since the world welcomed in 2023, Ukraine has stopped more than 80 drone strikes.

"We have information that Russia is planning a prolonged attack with Shaheds," he said.

UKRAINE LIBERATES 40% OF TERRITORY OCCUPIED BY RUSSIA SINCE FEB 2022: OFFICIAL

Zelenskyy said that Russia is looking to exhaust "our people, our air defense, our energy sector" by constantly pummeling the country with air strikes – a strategy Moscow has been employing for months but which it has escalated as winter sets in. 

"Now is the time when everyone involved in the protection of the sky should be especially attentive," he said addressing Ukrainian pilots and those in charge of air defense. 

"Our task is to give Ukraine every day successes," he continued. "Each shot down drone, each shot down missile, each day with electricity for our people and minimal schedules of blackouts are exactly such victories."

RUSSIAN DRONE SWARM CONTINUES NEW YEAR ASSAULT ON KYIV

Moscow and Tehran, Iran, have repeatedly denied any drone partnership or the use of Iranian supplied drones in Ukraine despite evidence supplied by Kyiv and backed by Western defense officials. 

Zelenskyy urged his forces on the front lines, particularly those fighting in areas like Bakhmut – which has seen intense ground warfare for months – to continue to hold the line amid harsh winter conditions, which has likely slowed fighting in other areas like Kherson. 

"No matter how difficult it is now, we must endure it. For it to be easier at the end of this winter," he said.
