People in the Philippines are voting for a new president and other leaders, with outspoken mayor Rodrigo “Digong” Duterte the favourite to win.
Five candidates are running but Mr Duterte led polls ahead of voting, despite controversial comments while campaigning and a hardline stance.
The campaign has been driven by public concerns about the economy, inequality and rampant corruption.
More than 100,000 police officers are on duty amid violence ahead of voting.
On Monday, seven people were shot dead in an ambush by unknown gunmen in the town of Rosario, in Cavite province, south of the capital, Manila.

On Saturday, a mayoral candidate was murdered in the south of the country.
President Benigno “Noynoy” Aquino is standing down as the constitution limits presidents to one six-year term. Filipinos will also pick a vice-president and local officials.

Mr Duterte has run a campaign focused on law and order issues, but made many controversial statements, including saying that he would butcher criminals.
