In the Philippines, voting in the national and local elections has been extended by one hour after problems with new automated vote counting machines led to long queues at polling stations. Six people have been killed as voters cast their ballots, amid reports of continuing violence in the south. There is a big security presence to prevent a repeat of pre-election bloodshed. Voters will elect a new president and vice-president, as well as more than 17,000 other positions. Benigno Aquino, the son of the popular former president, Cory Aquino, has been leading the polls but former president Joseph Estrada is also in the running. Dozens of people were killed during an intense three-month campaign.
