Russia is stepping up its use of S-300 and S-400 air defence systems to conduct strikes on ground targets, suggesting that Moscow's stocks of ballistic missiles are running low, Ukraine's Air Force spokesman said on Monday.
The official, Yuriy Ihnat, cited Ukrainian intelligence as claiming that Russia had fewer than 100 modern Iskander ballistic munitions left. He said Russia was, instead, using its S-300 and S-400 systems because of an abundance of munitions.
