The United States and its NATO allies have sent air defense systems to Ukraine, CNN reported, citing an unnamed senior U.S. official.

"The United States and its NATO allies are already sending several surface-to-air missile systems to Ukraine to help defend it. According to a senior U.S. official, these additional systems include mobile Soviet-era SA-8, SA-10, SA-12 and SA-14 air defense systems," the report said.

It specifies that these systems have a lower altitude range than the S-300 system requested by Ukraine, but have a higher range than the Stinger missiles previously delivered to Ukraine, giving them the ability to hit cruise missiles.

"According to this senior U.S. official, the systems have been received from NATO partner countries and are 'on their way,'" the publication reported.
