- I think people all over the world see these types of events for what they are, Pompeo says in a radio interview, and continues:

- I do not think it is good for the Russian people.

Navalny fell ill on a flight between Siberian Tomsk and Moscow on August 20, and the plane made an emergency landing in Omsk.

His co-workers immediately said that they thought Navalny was poisoned when he drank a cup of tea at the airport and the hospital in Omsk admitted him to the toxicology department.

Two days later, Navalny flew to Berlin to be cared for at the Charité Hospital.

He has been awakened from the artificial coma he has been put in and is responding to charges, the hospital in Berlin announced on Monday.

Pompeo: "We will evaluate"

Pompeo says the United States wants to help find out who is to blame.

- This is something that we will look at, that we will evaluate, and we will do everything we can to reduce the risk of similar things happening again.

US President Donald Trump has previously said he has not seen any evidence that Navalny was poisoned.
