Afghanistan boosts security for presidential election

A massive security operation is in place across Afghanistan for the country’s presidential election on Saturday.

About 100,000 security personnel are to guard polling stations in the wake of Taliban threats.

The fear of reprisals means many voters – particularly in rural areas – will stay at home, while others say the voting system favours the powerful, not the poor.
