(Tut.By via AP)MOSCOW Authorities in Belarus detained scores of university students who took to the streets Tuesday to demand that authoritarian President Alexander Lukashenko resign after an election the opposition has denounced as rigged. Police cordons forced the demonstrators to change their route, and they detained dozens of them, according to the Viasna human rights center. Students and universities in general are a highly explosive group, Stefanovich said in a telephone interview. One protester, Tatyana Ivanova, said that students from the Minsk State Linguistics University ran into a campus building to avoid being detained, but police tracked them down there. The president bristled at the idea and alleged the opposition would wage a massacre on his allies if it takes power in Belarus.
