"After additional inspection of the accident scene on the US embassy’s territory in Ukraine, police see signs of criminal offense, under part 4 article 296 ("hooliganism") of the Ukrainian Criminal Code," the national police said.
The statement specified that the decision to qualify the incident as hooliganism was made based on the reason that the item, thrown onto the embassy’s territory, could not harm anybody.
The national police supervise the investigation into the case, the statement added, stressing that Ukraine’s security services were reviewing the account that the offense could have been perpetrated with terror goals in mind.
Earlier in the day, the US embassy in Kiev posted a statement on its Facebook account, saying it did not regard the incident as a terror attack.
