Russia staged war games on Saturday in Kaliningrad — an enclave on the Baltic Sea sandwiched between Poland and Lithuania — Interfax news agency cited the Baltic Fleet Command as saying.

“Up to 1,000 military personnel... and more than 60 military equipment units were involved in the control checks,” Interfax news quoted the Russian Baltic Fleet Command’s press service as saying.

Separately, 20 Su-27 fighters and Su-24 front-line naval aviation bombers conducted planned combat training overnight, simulating attacks on low-speed air and ground targets, command posts and military equipment in Kaliningrad, Interfax said.
