Russia’s Foreign Ministry has said that if the United States decided to supply Kyiv with longer-range missiles, it would cross a “red line” and become “a party to the conflict” in Ukraine.

Washington has openly supplied Ukraine with advanced guided multiple launch rocket system (GMLRS) rockets, which are fired from high mobility artillery rocket system (HIMARS) launchers and which can hit targets up to 80km (50 miles) away.

HIMARS launchers can also be used to fire longer-range ATACMS tactical missiles, which can have a range of up to 300km (186 miles). A senior Ukrainian official declined to say on August 19 whether Kyiv now had ATACMS.

There has been no full public explanation of an attack on August 9 that hit a Russian air base at Saky, around 200km (124 miles) from the nearest Ukrainian-controlled territory, on the Crimean Peninsula, which Moscow annexed in 2014 in a move not recognised by the international community.
