Three dead in graduation shooting at top Philippines university

Three people died in a shooting at a university graduation ceremony in the Philippines' capital region on Sunday.

Local Quezon City police chief Remus Medina said the shooting appeared to have been an assassination of the former mayor of the southern Lamitan city, Rose Furigay.

The suspect, wounded in a shootout with a campus security officer and arrested after a car chase, was now in custody and being interrogated, Medina told reporters.

"He looks like he was a determined assassin," Medina said, adding he was found with two pistols.

Quezon is part of the Manila capital region, an urban sprawl of 16 cities home to more than 13 million people.

Furigay was shot as she was about to attend the graduation of her daughter at the law school of Ateneo de Manila University, one of the country's most prestigious, Medina said.

The suspect, who had no relatives at the graduation, was also a native of Lamitan city in Basilan province, a stronghold of Abu Sayyaf, a pro-IS extremist group known for its banditry and kidnapping.

The two others killed were a campus security officer and an unidentified male, the police said.

Ateneo cancelled the graduation ceremony after the shooting.

"We commit our law enforcement agencies to thoroughly and swiftly investigate these killings and bring all involved to justice," Philippines President Ferdinand Marcos Jr said in a statement.
