Moscow warns US over Ukraine's potential use of longer-range missiles

Moscow has warned the U.S. that allowing Ukraine to use longer-range missiles against targets in Russia will escalate tensions in the ongoing conflict. This warning follows President Biden's recent policy shift on military support for Ukraine. The change comes as Russia increases missile production, with satellite images showing significant expansions at five missile engine complexes. This development coincides with recent missile strikes in Ukraine that resulted in multiple civilian casualties. U.S. officials confirmed that restrictions on Ukraine's use of the Army Tactical Missile System are being eased. This marks a significant change after months of limiting Ukraine's strike capabilities to avoid direct confrontation with Russia.
