According to the broadcaster, it looks like "the Russians had a special group" and followed Skripal well before "attempting to kill him."
The sources cited by the broadcaster said that Skripal visited the Czech Republic to assist local intelligence with the discovery of possible Russian spies in the country. The sources are convinced that Boshirov and Petrov already tracked Skripal at that time, the publication claimed.
According to the publication, Petrov lived in a hotel in the city of Ostrava in the country's northeast from October 13 to October 16, 2014, and then moved to Prague, while Boshirov visited Prague on October 11, 2014.
Russian Embassy in Prague told the publication that the questions about crossing the border of the Czech Republic by citizens of other states are within the competence of the relevant Czech authorities.
In early September, UK prosecutors charged Petrov and Boshirov with the attempted murder of the Skripals and UK police officer Nick Bailey in the UK city of Salisbury in March. UK Prime Minister Theresa May expressed a belief that the suspects worked for the Main Directorate of the General Staff of the Russian Armed Forces (formerly known as the GRU), albeit without providing any evidence.
Russian Deputy Interior Minister Igor Zubov has said that "the Directorate of the Federal Migration Service has no departments that were subordinates of the GRU or someone else." He added that it was impossible to understand whether a person works in the GRU just by looking at the migration service’s database. The Russian Foreign Ministry’s spokeswoman, Maria Zakharova, has also criticized the materials issued by Bellingcat.
