Medical officials within the activists' camp have claimed that three activists have died in the latest clashes with riot police.
Prime Minister Mykola Azarov has claimed the police at the site of the clashes did not have live ammunition.
However, the Associated Press is now reporting that prosecutors say that the two men "were shot with live ammunition."
However, there are some reports that the activist did not fall off the roof, but was "thrown" off.
There's also disturbing video footage that some are saying shows what happened on the colonnade.
With regards to the one confirmed death, there are reports on Twitter that the activist was male and was shot multiple times.
The details of the activist's death are unconfirmed, but there are some reports the activist was shot by a police sniper.
The following photo of the activist has been circulated on Twitter and used by the BBC.
The AP reports that police have now torn down barricades at the protestors' camp, and are chasing away protestors from the area.
Prime Minister Mykola Azarov has stated that the opposition leaders should be held responsible for the deaths.
The U.S. Embassy has since announced it has revoked the visas of several Ukrainians who were linked to the violence in Kiev, "in response to actions taken against protestors on the Maidan in November and December of last year."
