On Tuesday, three members of the Estonian parliament, who had previously been banned from entering Russia, tabled a motion, which is meant to ban four Russian citizens from entering Estonia and other Schengen Area nations. According to the lawmakers, these individuals may be linked to the recent naval incident between Russia and Ukraine in the Kerch Strait.

The proposed list of "unwanted" Russian nationals includes first deputy director of the Russian Federal Security Service (FSB), Gen. Vladimir Kulishov; chief of the FSB border guard service in Crimea and Sevastopol, Rear Adm. Sergei Stankevich; the chair of the Russian lower house’s committee on security and anti-corruption, Vasily Piskarev; and the chair of the upper house's information policy commission, Alexey Pushkov.
On November 25, Ukraine's Berdyansk and Nikopol gunboats and the Yany Kapu tugboat illegally crossed the Russian maritime border as they sailed toward the Kerch Strait, the entrance to the Sea of Azov. Russia seized the Ukrainian vessels and detained 24 crew members after they failed to respond to a demand to stop. Russian President Vladimir Putin has said that the incident was a provocation prepared in advance as a pretext to introduce martial law ahead of Ukraine's upcoming presidential election.
