"This action by Ukraine was an absolutely illegal and unjustified act, contrary to the Charter of the United Nations, as well as a dangerous act of adventurism that will certainly not go unanswered by us," Baghaei said in a weekly press briefing, adding that the consequences of Ukraine's action "will certainly be unforeseen."
