THE HAGUE/MANILA - Former Philippine President Rodrigo Duterte, who has been in the Netherlands, said on Thursday that he will take responsibility for everything during his presidency.

In a video posted on the Rody Duterte Facebook page, the former president said he expected a long legal proceeding, and that he will continue to serve his country.

"To my countrymen, just to give you the current situation, I am about to land in The Hague after a stopover in Dubai. It's a long-haul flight. I'm ok. Do not worry," Duterte said in the video.

"And I think this has something to do with the law and order back then, and I told the police and military to just do their job and I will take responsibility. So here it is," he said.

"For all of the whatever happened in the past, I am the one who stood in front of our law enforcers and the military. I told them that I will protect you...I will take responsibility for everything," the former president said.

"This will be a long legal proceeding but I say to you I will continue to serve my country. So be it if that is my destiny," Duterte continued.

The video, taken inside the chartered plane carrying Duterte to The Hague, was posted before his plane landed at Rotterdam The Hague Airport in the Netherlands.

Duterte, who is turning 80 on March 28, was detained on Tuesday morning upon his return to Manila from abroad, following an arrest warrant issued by the International Criminal Court (ICC) over his "war on drugs" campaign, a move he has questioned.

He left Manila for The Hague, home to the ICC, on Tuesday night.

And the plane carrying Duterte arrived on Wednesday afternoon at Rotterdam The Hague Airport in the Netherlands.

In an emailed response to Xinhua on Wednesday, ICC spokesperson Fadi El Abdallah confirmed Duterte's arrival in the Netherlands.

"Once a suspect is in ICC custody, an initial appearance hearing will be scheduled," the spokesman said in an earlier email reply on Wednesday, adding that further details "will be communicated in due course."

Meanwhile, Philippine Vice-President Sara Duterte departed for the Netherlands on Wednesday morning. She had previously stated that she would accompany her father to The Hague for the ICC proceedings.

Rotterdam The Hague Airport, located northwest of Rotterdam, is approximately 20 km from The Hague.

Separately, Duterte is still a candidate for mayor of Davao City in the 2025 midterm elections despite his current detention in The Hague in the Netherlands, a chief of the Philippine Commission on Elections (Comelec) has said.

"As far as the Comelec is concerned, he (Duterte) is still a candidate. His name is on the ballot, and voters can vote for him," George Garcia told reporters on Wednesday.

Garcia said, "The arrest of a person accused of a crime, even in our own country, is not a sign to remove the candidate's name (from the ballot), disqualify him, or deprive him of his civil or political rights."

On May 12, Filipinos will vote in the midterm elections to elect 12 senators, new members of the House of Representatives, and local leaders.

Duterte had served as mayor of Davao, a southern metropolis, for 22 years before he became Philippine president in 2016.
