Belarus security services detained at least 450 protesters in the wake of rallies across the country against the strong-armed measures of President Alexander Lukashenko.
A blast at a metro station in the Belarusian capital Minsk killed seven people and injured about 50. The cause is not yet known.
Belarus President Alexander Lukashenko's crackdown on the opposition has prompted the EU to consider sanctions. But some members say that could backfire.
