An inspection will be carried out in the Tomsk airport coffee shop where, according to his supporters, Alexei Navalny drank tea shortly before his health deteriorated, its director Pyotr Filonenko told TASS.

"Yes, the CCTV footage will be scrutinized. Now I am going to the coffee shop, and we will look into the matter," he promised.
