OTTAWA - Foreign Affairs Minister John Baird says Afghans have demonstrated their commitment to a democratic future, and now a new government must demonstrate that commitment as well.

Baird commented after Afghans defied a threat of Taliban violence and flocked to polling stations on Saturday in numbers so high that some centres ran out of ballots, and others stayed open late.

Baird noted that an unprecedented number of Afghan women turned out.

Voters are choosing from a field of eight presidential candidates, and a runoff is widely expected since none is likely to get the majority needed for an outright victory.

President Hamid Karzai was constitutionally barred from seeking a third term.

Partial results are expected as early as Sunday.
