Argentine Justin Bieber fans protest

Argentine fans of Justin Bieber protest in Buenos Aires, calling for their government to let the pop star perform in the country.

BUENOS AIRES (Reuters) - Hundreds of "Beliebers" protest in Buenos Aires. They want the government to let Justin Bieber perform in Argentina.

The pop star said on Twitter he can't, due to "legal conditions".

They may be related to accusations of assault in 2013. Bieber allegedly lashed out at an Argentine photographer who tried to take his picture.
