Iranian officials, after days of denials, admitted Jan. 11, 2020, that Tehran was responsible for mistakenly downing a Ukrainian airliner early on Jan. 8. The shootdown came hours after Iran launched a ballistic missile attack on two military bases housing U.S. troops in Iraq in retaliation for the U.S. killing of a top Iranian general. Iran’s admission sparked anti-government protests in Tehran. Demonstrators gathered at two universities, where some called for the resignation of their country's leaders.
