Iran is set to deliver Fath-360 missile launchers to Russia, Western and regional officials report, marking a new phase in Tehran’s military support for Moscow’s war in Ukraine.

The launchers, which are due soon, will allow Russia to utilize the 120-kilometer-range missiles that were purportedly supplied last year but did not have delivery systems. Their deployment may target Ukrainian military and border areas, according to Reuters.

Neither Iran nor Russia have verified the move. US and European officials say Iran has already provided drones, artillery, and over 400 short-range ballistic missiles to Russia.
