US surveillance data ‘crucial’: Ukrainian commander

Ukrainian Lieutenant General Serhiy Nayev told ABC News in an interview that the U.S. provides “surveillance data,” allowing the Ukrainian Armed Forces to more accurately pinpoint Russian targets within Ukraine’s borders.”This help is crucial for us,” he said.

Nayev said he was in “constant contact” with American generals stationed in other parts of Europe. An exchange of data between the Ukrainians and Americans helped the Ukrainian military to pinpoint targets using US-supplied HIMARS rocket systems.

“This work goes perfectly in real time,” he said.

Russian missile comes within 22 miles of Romanian border with Ukraine

Romania, a member of NATO, said Friday a Russian missile had come within 22 miles of its border but that it did not cross into the country’s territory, countering a claim made by the Ukrainian military.”The Romanian Air Forces’ air surveillance system detected on Friday, February 10th, an aerial target launched by a Russian Federation’s ship, navigating in the Black Sea, nearby the Crimean Peninsula. The target is most likely a cruise missile, which flew over the air space of Ukraine and the Republic of Moldova and reentered the Ukrainian air space without ever infringing Romania’s air space,” Romanian Defense Minister Angel Tîlvăr said in a statement Friday.

Ukrainian officials had said earlier Friday that two Russian missiles crossed into the airspace of Moldova and Romania before entering Ukraine and being directed at targets in the country.

“Several Russian missiles passed through the airspace of Moldova and Romania. These missiles are a challenge to NATO and collective security. This is terror that can and must be stopped,” Zelenskyy said Friday.

US providing coordinates for Ukraine’s strikes with HIMARS, Ukrainian official says

A Ukrainian official has confirmed to ABC News that the United States provides coordinates to Ukraine for most strikes carried out in Russian-occupied areas of the country, using the U.S.-supplied HIMARS rocket launchers.The Washington Post was first to report the news on Thursday, stating in an article: “Ukrainian officials said they require coordinates provided or confirmed by the United States and its allies for the vast majority of strikes using its advanced U.S.-provided rocket systems, a previously undisclosed practice that reveals a deeper and more operationally active role for the Pentagon in the war.”

The Ukrainian official who spoke with ABC News on Friday confirmed that Ukraine’s ability to strike targets with high precision has been thanks to support from the U.S. The official said Ukrainians wanted to get the maximum of out of every HIMARS.

“We get help for maximum effectiveness,” the official added.

And more broadly, the official said the cooperation between Ukraine and the U.S. in the war “is very close.”

Meanwhile, a senior Ukrainian official told ABC News on Friday that The Washington Post’s article “overestimates” the “role of the U.S. in the shooting process” of the HIMARS.

The senior official did not deny that the U.S. is involved in helping the Ukrainian military pinpoint targets with the U.S.-supplied HIMARS, but did not provide further detail.
