KYIV, Ukraine (AP) — President Alexander Lukashenko of Belarus has been sworn in to his sixth term in office at an inaugural ceremony that was not announced in advance amid weeks of huge protests. Opponents of the authoritarian leader say his reelection was rigged. Several European countries used the occasion to reiterate that they don’t recognize the results of the Aug. 9 election and refused to regard Lukashenko as the legitimate president. The state news agency said the ceremony was held in front of several hundred dignitaries at the ornate Palace of Independence in the capital of Minsk. Police and other security forces blocked off parts of the city and public transportation was suspended.
