Voter registration centres have been set up across Afghanistan in preparation for long-delayed parliamentary elections due to be held in October.

Election officials have acknowledged that security is a major concern as the Taliban and other militant groups control or contest large area of the country.

Afghan police and troops forces have been tasked with protecting polling centres, even as they struggle to get the upper hand against militants on the battlefield.
