Iranian trainers on ground help Russia with Ukraine drone attacks, says US

The United States has said that Iranian military trainers were in Crimea helping Russian forces operate Iranian-made drones to attack targets in Ukraine, adding an alarming strand to a war that has heightened geopolitical tensions.

Ukrainian citizens endured the first day of nationwide scheduled power outages since the war began eight months ago so repairs could be made to damaged or destroyed energy plants as winter approaches, India-based DD news reports.

"We can confirm that Russian military personnel based in Crimea have been piloting Iranian UAVs and using them to conduct kinetic strikes across Ukraine, including in strikes against Kyiv in recent days," US State Department spokesman Ned Price told a briefing with reporters, referring to unmanned aerial vehicles, or drones.

"We assess that ... Iranian military personnel were on the ground in Crimea and assisted Russia in these operations," Price said. He said "we do have credible information" but he did not provide evidence.

Russia seized Crimea from Ukraine in 2014 and has used the southern peninsula to train soldiers and reopen Soviet-era military bases as part of the invasion of its neighbour.

There was no immediate public reaction from Tehran to the US accusations but Iran has denied the drones are Iranian-made. Russia has also denied using Iranian drones in Ukraine.

Russia's defence and foreign ministries did not immediately respond to requests for comment.

White House national security spokesperson John Kirby told reporters that Washington was going to pursue all means to "expose, deter and confront" Iran's supply of munitions to Russia, including more sanctions, while also considering air defences for Ukraine.

European Union members have agreed on new measures against Iran, the bloc said, while Britain imposed sanctions on senior military figures and a firm it said was involved in the supply of Iranian drones to Moscow.

Russia and Iran have also been involved in the 11-year-long war in Syria, together supporting Syrian President Bashar al-Assad.

"Iran and Russia, they can lie to the world, but they certainly can't hide the facts, and the fact is this: Tehran is now directly engaged on the ground," Kirby said, without providing details.

Ukrainian Foreign Minister Dmytro Kuleba said on Twitter he had held detailed discussions with Israeli Prime Minister Yair Lapid on a request for air and missile defence systems and technology. Lapid's office said the Israeli leader expressed "deep concern" about the military connection between Iran and Russia.

People across Ukraine were urged to use less power as the government enforced electricity curbs between 7 a.m. and 11 p.m. on October 20.

The first such restrictions since Russia's February 24 invasion included blackouts in some areas and followed a barrage of Russian attacks that President Volodymyr Zelenskyy said had struck a third of all power plants.

"Restoring the electricity grid ... will take a certain amount of time, and we are not talking about days or even weeks. In order to restore the reliability of our energy system, several weeks will be needed," said Volodymyr Kudritskiy, chairman of the board of the national energy company Ukrenergo.

That estimate was conditional on an end to mass shelling, he said.

The northeast region of Sumy went without water as some grocery shops in the capital Kyiv reported brisk bottled water sales.
