Portuguese F-16 jets, operating as part of a NATO mission, intercepted Russian An-12 transport and Su-35 fighter aircraft over the Baltic Sea, marking another incident of non-compliance with international flight regulations.

Russia's Su-35 fighter jets are becoming a greater threat due to the integration of longer-range missiles, according to analysts.

Russia is set to continue supplying Yak-130 and Su-35 aircraft to Iran under an existing contract, with deliveries expected to last until at least 2026.

Norwegian armed forces observed a Russian Su-35S fighter jet, leading to speculation about potential supply shortages within the Russian army.
