BY A STAFF REPORTER: Andriy Yarmak, head of ukraine's presidential office, said the Russian missiles fired overnight in Ukraine were made using foreign chips. These missiles were developed by the Russians this year. The KH-101 has about 30 foreign chips, which were made in April.
"We gather information, work with our partners and communicate with them regularly. Our partner governments are also working with chip makers and suppliers. Sanctions have already been imposed, but sanctions need to be tightened to prevent Russia from acquiring critical components and producing missiles. "
Russia has carried out several missile strikes in Lviv in western Ukraine and other areas away from the front line, officials said.
