MANILA, Philippines – Bullet-ridden bodies were pulled out from shallow graves on Tuesday as troops hunted down the gunmen who massacred, according to the Philippine National Police, 24 people in one of the Philippines' most brutal explosions of political violence.

Police recovered the bodies following Monday’s carnage allegedly perpetrated by suspected armed followers of an influential political clan in Maguindanao province.

Chief Superintendent Leonardo Espina, PNP spokesman, said the bodies would be taken to Buluan town, Maguindanao province, after the police have conducted an autopsy on the bodies and conferred with the victims’ relatives.

Most of the victims bore gunshot wounds, Espina said.

The initial list of victims include Bai Farina Mangudadatu, Bai Eden Mangudadatu, Cynthia Oquindo, Connie Brizuela, Rasul Daud, Faridah Sabdula, Rowena Mangudadatu, Ayos Sudlang, Abdula Dodong, Divina dela Cruz, a certain Chito, Henry Araneta, Jimmy Cabello, a certain Jonto, Juanita Dalim, Mary Ann Calimbol, Ralda Sapalon, Pingky Sulaim, Rahima Palawan, Wahid Sabdula, Lilia del Macio, Patrika Palapay, Victor Munuz and a certain Mamot.

The victims were among a group of more than 40 people abducted by gunmen Monday linked to Maguindanao Governor Andal Ampatuan, head of a Muslim clan who is part of President Gloria Macapagal-Arroyo's ruling coalition.

The abducted group was made up of relatives and associates of Esmael Mangudadatu, the head of a rival Muslim clan in Maguindanao, plus a group of journalists, the military and police said.

The group was traveling in a convoy to accompany or report on Mangudadatu's wife as she went to an electoral office to register her husband to run for governor against Ampatuan's son in next year's national polls.

Authorities warned the death toll would climb higher as they sought to deal with the incident.

"It's a big area where these bodies were found. They are finding a couple of bodies every a couple of hours or so," Interior Secretary Ronaldo Puno said as he described a farming area covered in hastily dug graves.

Puno said the extra bodies being recovered were on top of the the official death toll, but he would not speculate on how many people in total had been murdered.

"They are still looking for some missing persons. A number of other bodies were found. I can't really reveal the details now. It's a large number," Puno said in a television interview.

Espina said PNP chief Jesus Verzosa and other senior police officials flew to Maguindanao early Tuesday to personally check on the area and supervise the manhunt against the perpetrators of the killings.

He said Verzosa ordered relief of Chief Inspector Sukarno Dicay, the deputy provincial police chief of Maguindanao, after he was supposedly seen with the armed men who abducted and killed the victims.

Additional police troops were also deployed in the area to prevent a possible rise of hostilities in the area.

Political violence is common in the Philippines – where more than one million unlicensed guns proliferate – and dozens of people are murdered each election season.

But the scale of Monday's massacre, as well as the targeting of apparently unrelated people, has shocked the country.

Fourteen of the victims were women and some of them were journalists with no apparent links to the clan war, the police and military said.

Military spokesman Lieutenant-Colonel Romeo Brawner said the Ampatuans and their associates were believed to have been responsible for the massacre.

"The suspects are bodyguards of Ampatuan, local police aides and certain lawless elements," Brawner said.

As thousands of soldiers fanned out across the Ampatuans' stronghold in search of the gunmen on Tuesday, sickening details of the massacre emerged.

The military said about 100 armed men stopped the convoy of vehicles on a remote section of highway near the town of Ampatuan, which bears the same name as the political kingpin.

Police said the bodies of the victims were found a few kilometers (miles) away, with a bulldozer apparently used to dig the graves still on the scene.

Police said 15 of the victims appeared to have been shot inside their vehicles while one was believed to have been cut down by gunfire while fleeing.

"All were shot at close range," said one of the investigators on the scene, Chief Superintendent Felicisimo Khu.

Asked about the allegations by some of the victims' relatives that the murdered women were also raped, Khu said: "We cannot confirm that although all the women had their pants unzipped."

The Ampatuan clan is the longtime political kingpin of Maguindanao, a mainly Muslim section of Mindanao Island which has been wracked by a Muslim separatist rebellion for decades.

The Ampatuan patriarch, Andal Ampatuan Sr., has been governor for the past nine years and wants his son and namesake to succeed him.

The Ampatuan clan has been important in delivering votes to Arroyo's ruling Lakas Kampi-CMD coalition in recent elections. The Ampatuan father is the provincial chair of the coalition in Maguindanao.

Puno vowed the government would be impartial as it pursued justice.

"I just want to assure everybody that we are doing everything necessary here, that there will be no sacred cows," Puno said.

"This is going to be a direct investigation of the crimes that have been committed and we are going to hold the persons responsible for this." (Marlon Ramos, Agence France-Presse, Philippine Daily Inquirer)
