Riot police clashed on Saturday with protesters in Belgrade, where an international Pride march started despite threats from anti-gay groups and an official earlier ban.

Tensions were high in the Serbian capital as protesters hurled stun grenades, stones and flares at a police cordon, which repelled the attack with batons and riot shields.
