Zelenskyy: Russia using Iranian weapons in 'massive' attack targeting energy infrastructure

Russian forces launched hundreds of drones and missiles targeting Ukraine's energy and power plant infrastructure on Sunday.

Ukrainian President Volodymyr Zelenskyy said the attack included at least 120 missiles and 90 drones, including Iranian-made Shahed drones. Ukrainian officials say it was the largest long-range attack from Russia in at least three months.

"The enemy's target was our energy infrastructure throughout Ukraine. Unfortunately, there is damage to objects from hits and falling debris. In Mykolaiv, as a result of a drone attack, two people were killed and six others were injured, including two children," Zelenskyy said.

Zelenskyy added that Ukrianian forces were able to shoot down 144 of the projectiles before they reached their targets.

Explosions were reported in the Ukrianian cities of Kyiv, Odesa, Zaporizhzhia, Kryvyi Rih, Dnipro and in western Ukraine. Odesa, a port city, was reportedly left without power.

Poland's military reacted to the attack by scrambling its own airforce within its borders, though there were no reports of Russian ordnance falling on Polish soil.

DOCUMENTS REVEAL RUSSIA'S INITIAL 'PEACE DEAL' EQUATED TO THE SURRENDER OF UKRAINE: REPORT

Russia has repeatedly targeted Ukraine's energy infrastructure as temperatures get colder in Ukraine, a strategy Mosocw has employed in previous years of the conflict.

The attack comes as President-elect Donald Trump is expected to soon appoint a Ukrainian peace envoy to lead negotiations on ending the war with Russia.

TRUMP'S FIRST CABINET PICKS DECIDEDLY NOT ISOLATIONISTS: UKRAINE, ISRAEL BREATHE A SIGH OF RELIEF

The job is not expected to be a salaried role - from 2017 to 2019, Kurt Volker had served as special representative to Ukrainian negotiations on a volunteer basis. 

Trump has been rolling out appointee names of those he wants to fill his Cabinet and advise him on top issues at a lightning-quick pace.

Trump has long insisted he could negotiate an end to the war with Ukrainian President Volodymyr Zelensky and Russian President Vladimir Putin. Few details have been given about how he would do this. 

Some advisers are reportedly encouraging Trump to push Kyiv to agree to terms that would freeze the frontlines by creating an 800-mile-long demilitarized zone and allow Russia to keep the land it has illegally seized, which amounts to roughly 20% of Ukraine.

It has also been suggested that Kyiv should agree not to pursue NATO membership for 20 years, a stipulation that critics of this plan argue kowtows to Putin.
