Riots erupt in Nigerian cities as bank policy leads to scarcity of cash

Angry protesters attack ATMs and block roads in frustration at lack of new banknotes days before election

Rioters have attacked bank ATMs and blocked roads in three Nigerian cities as anger spilled on the streets over a scarcity of cash, just days before the country's general election.

Nigeria has been struggling with a shortage in physical cash since the central bank began to swap old bills of the local naira currency for new ones, leading to a shortfall in banknotes.
