Millions of voters are casting ballots across Egypt to choose a new president, for the second time in two years.

A huge security operation has been mounted by police and the military, amid fear of attacks by militants seeking to disrupt the polls.

Former army chief Abdul Fattah al-Sisi, who deposed Islamist President Mohammed Morsi last year, is standing against left-wing candidate Hamdeen Sabahi.

Mr Sisi is forecast to win by a comfortable margin.

The elections are being held across two days, with unofficial results expected hours after polls close.
