Two men convicted of carrying out a deadly subway bombing last year in Belarus's capital have been executed, drawing strong condemnation from activists and the European Union.

At least two construction workers were injured and one was rushed to hospital following an accident at a subway tunnel excavation site near Toronto's York University.

Commuters around the world were subjected to riding the subway alongside half-dressed pranksters of every stripe, thanks to an annual event that has spread to dozens of countries.
