(Reuters) - Security forces in Belarus detained scores of protesters and were filmed beating a man as he lay on the street, as the authorities launched a crackdown on mass demonstrations against President Alexander Lukashenko.
Nearly a month after an election which Lukashenko's opponents say he rigged, tens of thousands of people marched through Minsk, many decked out in red-and-white opposition colours and shouting "go away!" and "you're a rat!".
